Functional Description

The TLE 4295 G is a monolithic integrated low-drop voltage regulator in the very small

SMD package PG-SCT595-5. It is designed to supply e.g. microprocessor systems

under the severe conditions of automotive applications. Therefore the device is equipped

with additional protection functions against overload, short circuit and reverse polarity.

At overtemperature the regulator is automatically turned off by the integrated thermal

protection circuit.

Input voltages up to 40 V are regulated to

Q,nom

= 2.6 V (V26 version) 3.0 V

(V30 version) 3.3 V (V33 version) or 5.0 V (V50 version). The output is able to drive a

load of more than 30 mA while it regulates the output voltage within a 4% accuracy.

The power fail output (open collector) is switched to low in case of undervoltage overload

or saturation of the output transistor.
