Functional Description

The TLE 4470 is a monolithic integrated voltage

regulator with two very low-drop outputs, a main output Q2 for loads up to 350 mA and

a stand by output Q1 providing a maximum of 180 mA. The device is available in two

packages the PG-DSO-14 and PG-DSO-20. It is designed to supply microprocessor

systems under the severe conditions of automotive applications and is therefore

equipped with additional protection functions against overload, short circuit and

overtemperature. Of course the TLE 4470 can also be used in other applications where

two stabilized voltages are required.

The device operates in the wide junction temperature range of -40

°C to 150 °C.

The stand-by regulator transforms an input voltage
