DESCRIPTION

The REG102 is a family of low-noise, low-dropout linear

regulators with low ground pin current. The new DMOS

topology provides significant improvement over previous

designs, including low-dropout voltage (only 150mV typ at

full load), and better transient performance. In addition, no

output capacitor is required for stability, unlike conventional

low-dropout regulators that are difficult to compensate and

require expensive low ESR capacitors greater than 1μF.

Typical ground pin current is only 600μA (at I OUT = 250mA)

and drops to 10nA when not enabled. Unlike regulators with

PNP pass devices, quiescent current remains relatively con-

stant over load variations and under dropout conditions.

The REG102 has very low output noise (typically 28μVrms

for V OUT = 3.3V with C NR = 0.01μF), making it ideal for use

in portable communications equipment. On-chip trimming

results in high output voltage accuracy. Accuracy is main-

tained over temperature, line, and load variations. Key pa-

rameters are tested over the specified temperature range

(–40°C to +85°C).

The REG102 is well protected—internal circuitry provides a

current limit that protects the load from damage; furthermore,

thermal protection circuitry keeps the chip from being dam-

aged by excessive temperature. The REG102 is available in

SOT23-5, SOT223-5, and SO-8 packages.

ELECTROSTATIC

DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper han-dling and installation procedures can cause damage.ESD damage can range from subtle performance degrada-tion to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

ELECTRICAL CHARACTERISTICS

Boldface limits apply over the specified temperature range, T J = –40°C to +85°C.

At T J = +25°C, V IN = V OUT + 1V (V OUT = 2.5V for REG102-A), V ENABLE = 1.8V, I OUT = 5mA, C NR = 0.01μF, and C OUT = 0.1μF(1), unless otherwise noted.

NOTES: (1)The REG102 does not require a minimum output capacitor for stability, however, transient response can be improved with proper capacitor selection.

(2)Dropout voltage is defined as the input voltage minus the output voltage that produces a 2% change in the output voltage from the value at V IN = V OUT

+ 1V at fixed load.

(3)Current limit is the output current that produces a 10% change in output voltage from V IN = V OUT + 1V and I OUT = 5mA.

(4)For V ENABLE > 6.5V, see typical characteristic I ENABLE vs V ENABLE.

(5)The REG102 no longer regulates when V IN < V OUT + V DROP (MAX). In dropout, the impedance from V IN to V OUT is typically less than 1? at T J = +25°C.

BASIC OPERATION

The REG102 series of LDO (low dropout) linear regulators offers a wide selection of fixed output voltage versions and an adjustable output version as well. The REG102 belongs to a family of new generation LDO regulators that use a DMOS pass transistor to achieve ultra low-dropout perfor-mance and freedom from output capacitor constraints. Ground pin current remains under 1mA over all line, load, and temperature conditions. All versions have thermal and over-current protection, including foldback current limit.

The REG102 does not require an output capacitor for regulator stability and is stable over most output currents and with almost any value and type of output capacitor up to 10μF or more. For applications where the regulator output current drops below several milliamps, stability can be enhanced by adding a 1k ?to 2k ? load resistor, using capacitance values smaller than 10μF, or keeping the effective series resistance greater than 0.05? including the capacitor ESR and parasitic resistance in printed circuit board traces, solder joints, and sockets.Although an input capacitor is not required, it is a good standard analog design practice to connect a 0.1μF low ESR capacitor across the input supply voltage. This is recom-mended to counteract reactive input sources and improve ripple rejection by reducing input voltage ripple.

Figure 1 shows the basic circuit connections for the fixed voltage models. Figure 2 gives the connections for the adjust-able output version (REG102A) and example resistor values for some commonly used output voltages. Values for other volt-ages can be calculated from the equation shown in Figure 2.

INTERNAL CURRENT LIMIT

The REG102 internal current limit has a typical value of 400mA. A foldback feature limits the short-circuit current to a typical short-circuit value of 150mA, which helps to protect

the regulator from damage under all load conditions. A characteristic of V OUT versus I OUT is given in Figure 3 and in the Typical Characteristics section.

FIGURE 5. Output Noise versus Noise Reduction Capacitor.

ENABLE

The Enable pin is active high and compatible with standard TTL-CMOS levels. Inputs below 0.5V (max) turn the regula-tor off and all circuitry is disabled. Under this condition,ground pin current drops to approximately 10nA. When not used, the Enable pin can be connected to V IN . When a pull-up resistor is used, and operation below 1.8V is required, use pull-up resistor values below 50k ?.

OUTPUT NOISE

A precision bandgap reference is used to generate the internal reference voltage, V REF . This reference is the domi-nant noise source within the REG102 and generates approxi-mately 29μVrms in the 10Hz to 100kHz bandwidth at the reference output. The regulator control loop gains up the reference noise, so that the noise voltage of the regulator is approximately given by:

V Vrms

R R R Vrms V V N OUT

REF

=μ+=μ?2922912

(1)

As the value of V REF is 1.26V, this relationship reduces to:

V Vrms

V N OUT =μ?23

(2)

Connecting a capacitor, C NR , from the Noise Reduction (NR)pin to ground forms a low-pass filter for the voltage refer-ence. Adding C NR (as shown in Figure 4) forms a low-pass filter for the voltage reference. For C NR = 10nF, the total noise in the 10Hz to 100kHz bandwidth is reduced by approxi-mately a factor of 2.8 for V OUT = 3.3V. This noise reduction effect is shown in Figure 5 and as RMS Noise Voltage vs C NR in the Typical Characteristics section.

Noise can be further reduced by carefully choosing an output

capacitor, C OUT . Best overall noise performance is achieved with very low (< 0.22μF) or very high (> 2.2μF) values of C OUT (see the RMS Noise Voltage vs C OUT typical characteristic).The REG102 uses an internal charge pump to develop an internal supply voltage sufficient to drive the gate of the DMOS pass element above V IN . The charge-pump switching noise (nominal switching frequency = 2MHz) is not measur-able at the output of the regulator over most values of I OUT and C OUT .

The REG102 adjustable version does not have the noise-reduction pin available; however, the adjust pin is the sum-ming junction of the error amplifier. A capacitor, C FB , con-nected from the output to the adjust pin can reduce both the output noise and the peak error from a load transient (see the typical characteristics for output noise performance).

FIGURE 6. Transient and DC Dropout.

DROPOUT VOLTAGE

The REG102 uses an N-channel DMOS as the pass element.When (V IN – V OUT ) is less than the drop-out voltage (V DROP ),the DMOS pass device behaves like a resistor; therefore, for low values of (V IN – V OUT ), the regulator input-to-output resistance is the Rds ON of the DMOS pass element (typically 600m ?). For static (DC) loads, the REG102 typically main-tains regulation down to a (V IN – V OUT ) voltage drop of 150mV at full rated output current. In Figure 6, the bottom line (DC dropout) shows the minimum V IN to V OUT voltage drop re-quired to prevent dropout under DC load conditions.For large step changes in load current, the REG102 requires a larger voltage drop across it to avoid degraded transient response. The boundary of this transient drop-out region is shown as the top line in Figure 6 and values of V IN to V OUT voltage drop above this line insure normal transient re-sponse.

case conditions (full-scale load change with (V IN – V OUT )voltage drop close to DC dropout levels), the REG102 can take several hundred microseconds to re-enter the specified window of regulation.

TRANSIENT RESPONSE

The REG102 response to transient line and load conditions improves at lower output voltages. The addition of a capacitor (nominal value 0.47μF) from the output pin to ground can improve the transient response. In the adjustable version, the addition of a capacitor, C FB (nominal value 10nF), from the output to the adjust pin can also improve the transient response.

THERMAL PROTECTION

Power dissipated within the REG102 can cause the junction temperature to rise. The REG102 has thermal shutdown circuitry that protects the regulator from damage which dis-ables the output when the junction temperature reaches approximately 160°C, allowing the device to cool. When the junction temperature cools to approximately 140°C, the out-put circuitry is again enabled. Depending on various condi-tions, the thermal protection circuit can cycle on and off. This limits the dissipation of the regulator, but can have an undesirable effect on the load.

Any tendency to activate the thermal protection circuit indi-cates excessive power dissipation or an inadequate heat sink. For reliable operation, junction temperature must be limited to 125°C, maximum. To estimate the margin of safety in a complete design (including heat sink), increase the ambient temperature until the thermal protection is triggered;use worst-case loads and signal conditions. For good reliabil-ity, thermal protection should trigger more than 35°C above the maximum expected ambient condition of the application.This produces a worst-case junction temperature of 125°C at the highest expected ambient temperature and worst-case load.

The internal protection circuitry of the REG102 is designed to protect against overload conditions and is not intended to replace proper heat sinking. Continuously running the REG102into thermal shutdown will degrade reliability.

In the transient dropout region between DC and Transient,transient response recovery time increases. The time required to recover from a load transient is a function of both the magnitude and rate of the step change in load current and the available headroom V IN to V OUT voltage drop. Under worst-

FIGURE 8. Thermal Resistance versus PCB Area for the Five-Lead SOT-223.

POWER DISSIPATION

The REG102 is available in three different package configu-rations. The ability to remove heat from the die is different for each package type and, therefore, presents different consid-erations in the printed circuit board (PCB) layout. The PCB area around the device that is free of other components moves the heat from the device to the ambient air. Although it is difficult to impossible to quantify all of the variables in a thermal design of this type, performance data for several simplified configurations are shown in Figure 7. In all cases,the PCB copper area is bare copper (free of solder resist mask), not solder plated, and are for 1-ounce copper. Using heavier copper will increase the effectiveness in moving the heat from the device. In those examples where there is copper on both sides of the PCB, no connection has been provided between the two sides. The addition of plated through holes will improve the heat sink effectiveness.Power dissipation depends on input voltage, load conditions,and duty cycle and is equal to the product of the average output current times the voltage across the output element,V IN to V OUT voltage drop.

P V V I D IN OUT OUT

=?(–)(3)

Power dissipation can be minimized by using the lowest possible input voltage necessary to assure the required output voltage.

REGULATOR MOUNTING

The tab of the SOT-223 package is electrically connected to ground. For best thermal performance, this tab must be soldered directly to a circuit-board copper area. Increasing the copper area improves heat dissipation, as shown in Figure 8.

Although the tab of the SOT-223 is electrical ground, it is not intended to carry current. The copper pad that acts as a heat sink should be isolated from the rest of the circuit to prevent current flow through the device from the tab to the ground pin. Solder pad footprint recommendations for the various REG102 devices are presented in Application Bulletin Solder Pad Recommendations for Surface-Mount Devices (SBFA015), available from the Texas Instruments web site (https://www.wendangku.net/doc/bf972428.html,).
