Description

The TLE 42694 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 proof

by the implemented output current limitation and has an integrated

overtemperature shutdown. A reset signal is generated for an output

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. The reset and sense output

are internally connected to the output Q via a pull-up resistor. If these

integrated resistors are not desired, the TLE42794 can be used instead of the TLE42694.
