Functional Description

The TLE 4476 is a monolithic integrated voltage regulator providing two output voltages,

Q1 is a 3.3 V output for loads up to 350 mA and Q2 is a 5 V output providing 430 mA.

The device is available in the PG-TO252-5-11 (D-Pak) package. Output 2 can be

switched ON/OFF via the Enable input EN.

The TLE 4476 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.
