Description

The TLE42794G is a monolithic integrated low dropout voltage

regulator, especially designed for automotive applications. An input

voltage up to 45 V is regulated to an output voltage of 5.0 V. The

component is able to drive loads up to 150 mA. It is short-circuit

protected 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. This threshold can be decreased by

an external resistor divider. The power-on reset delay time can be

programmed by the external delay capacitor. The additional sense

comparator provides an early warning function: Any voltage (e.g. the

input voltage) can be monitored, an under-voltage condition is indicated

by setting the comparator’s output to low. If pull-up resistors are desired

at the outputs of the reset and the sense comparator, the TLE42694 with

integrated pull-up reistors can be used instead of the TLE42794.
