Dual Low Drop Voltage Regulator TLE 4476 Features Output 1: 350 mA 3.3 V 4% Output 2: 430 mA 5.0 V 4% Enable input for output 2 Low quiescent current in OFF state Wide operation range: up to 42 V P-TO252-5-11 Reverse battery protection: up to 42 V Output protected against short circuit Wide temperature range: -40 C to 170 C Overvoltage protection up to 65 V (< 400 ms) Overtemperature protection Overload protection Green Product (RoHS compliant) AEC Qualified 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 TLE4476 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.
