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 V

Q,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 C

is recommended for compensation of line

influences. An output capacitor C

is necessary for the stability of the

control loop.
