Description

The TLE42754 is a monolithic integrated low-dropout voltage

regulator in a 5-pin TO-package, especially designed for automotive

applications. An input voltage up to 42 V is regulated to an output

voltage of 5.0 V. The component is able to drive loads up to

450 mA. It is short-circuit proof by the implemented current limitation

and has an integrated overtemperature shutdown. A reset signal is

generated for an output voltage VQ,rt of typically 4.65 V. The power-on

reset delay time can be programmed by the external delay capacitor.

Dimensioning Information on External Components

An input capacitor CI is recommended for compensation of line

influences. An output capacitor CQ is necessary for the stability of the

control loop.
