Functional Description

The TLE 4275 is a monolithic integrated low-drop voltage regulator in a 5-pin TO-package. An input voltage up to 45V is regulated to V Q,nom = 5.0 V. The IC is able to drive loads up to 450mA and is short-circuit proof. At overtemperature the TLE 4275 is turned off by the incorporated temperature protection. A reset signal is generated for an output voltage V Q,rt of typ. 4.65V.The delay time can be programmed by the external delay capacitor.

Dimensioning Information on External Components

The input capacitor C I is necessary for compensation of line influences. Using a resistor of approx. 1? in series with C I, the oscillating of input inductivity and input capacitance can be damped. The output capacitor C Q is necessary for the stability of the regulation circuit. Stability is guaranteed at values C Q≥ 22 μF and an ESR of ≤ 5 ? within the operating temperature range.

Circuit Description

The control amplifier compares a reference voltage to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. Saturation control as a function of the load current prevents any oversaturation of the power element. The IC also incorporates a number of internal circuits for protection against:

?Overload

?Overtemperature

?Reverse polarity
