Short Functional Description

The TLE 4252 is a monolithic integrated low-dropout voltage tracking regulator in a

PG-TO263-5 package. It is designed to supply off-board systems, e.g. sensors in engine

management systems under the severe conditions of automotive applications.

Therefore, the device is equipped with additional protection functions against reverse

polarity and short circuit to GND and battery.

With supply voltages up to 40 V, the output voltage follows a reference voltage with high

accuracy. The reference voltage can be applied directly to the adjust input or by an

external resistor divider. The minimum reference voltage at the component’s pin is 1.5 V.

The output is able to drive loads up to 250 mA following e.g. the 5 V output of a main

voltage regulator as reference.

The TLE 4252 tracking regulator can be switched into stand-by mode to reduce the

current consumption to less than 2µA. This feature makes the IC suitable for low power

battery applications.

This product is also available in a PG-TO252-5 package. See datasheet “TLE 4252 D”.
