L4945 Datasheet - STMicroelectronics

L4945 5V VERY LOW DROP VOLTAGE REGULATOR

The L4945 is a monolithic integrated circuit in Versawatt package specially designed to provide a stabilized supply voltage for automotive and industrial electronic systems. Thanks to their very low voltage drop, in automotive applications the devices can work correctly even during the crankBLOCK DI.
