Functional Description

The TLE 4251 is a monolithic integrated low drop voltage
tracker in the very small SMD package PG-TO252-5-1. It is designed to supply e.g. sensors under the severe

P-TO263-5-1
conditions of automotive applications. Therefore the
device is equipped with additional protection functions against overload, short circuit and

Supply voltages up to 40 V are tracked to a reference voltage given to the adjust input via an external resistor.

The output is able to drive loads up to 400 mA while it follows e.g. the 5 V output of a main voltage regulator within an accuracy of For loads up to 300 mA the tracking accuracy is

The TLE 4251 can be switched in stand-by mode via the enable EN input which causes the current consumption to drop to very low values. This feature makes the IC suitable for low power battery applications.
