P-TO252-5-11

Functional Description

The

TLE 4251

is a monolithic integrated low drop voltage

tracker in the very small SMD package PG-TO252-5-1. It

P-TO263-5-1

is designed to supply e.g. sensors under the severe

conditions of automotive applications. Therefore the

device is equipped with additional protection functions against overload, short circuit and

reverse polarity.

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 0.5%. For loads up to 300 mA the tracking

accuracy is 0.2%.

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.
