DESCRIPTION

The L2610CV three terminal positive regulator is specially designed to stabilize power supplies car instrumentation in vehicles with 12V battery.

Available with 10V output voltage, it can supply an output current to 500mA.This device is protected against load dump and field decay transients (±100V), reverse battery,short circuit and thermal overload.

ELECTRICAL CHARACTERISTCS (T j = 25 °C, V i = 14V, unless otherwise specified)

(*) Note: For DC innput voltage 28 V

ELECTRICAL CHARACTERISTCS (-40 ≤ T j ≤ 125 °C (note 2), V i = 14V, unless otherwise specified)

Notes:1.For a DC input voltage 26 V < V i < 35 V the device is not operating.

2.The limits are guarandeed by design correlation and statistical control on production samples over the indicated temperature and supply voltage ranges.
