Data Sheet, Rev. 1.1, January 2010 TLE42744 Low Dropout Linear Voltage Regulator Automotive Power Low Dropout Linear Voltage Regulator TLE42744 1 Features • • • • • • • • • • Overview Very Low Current Consumption Output Voltages 5 V and 3.3 V ±2% Output Current up to 400 mA Very Low Dropout Voltage Output Current Limitation Reverse Polarity Protection Overtemperature Shutdown Wide Temperature Range From -40 °C up to 150 °C Green Product (RoHS compliant) AEC Qualified PG-TO252-3 PG-SSOP-14 exposed pad PG-TO263-3 Description PG-SOT223-4 The TLE42744 is a monolithic integrated low dropout voltage regulator for load currents up to 400 mA. An input voltage up to 40 V is regulated to VQ,nom = 5 V / 3.3 V with a precision of ±2%. The device is designed for the harsh environment of automotive applications. Therefore it is protected against overload, short circuit and overtemperature conditions by the implemented output current limitation and the overtemperature shutdown circuit. The TLE42744 can be also used in all other applications requiring a stabilized 5 V / 3.3 V voltage. Due to its very low quiescent current the TLE42744 is dedicated for use in applications permanently connected to VBAT.
