Description
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
V
Q,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
V
