L4947R Overview
The L4947/L4947R is a monolithic integrated circuit in Pentawatt package specially designed to provide a stabilized supply voltage for automotive and industrial electronic systems. Thanks to its very low voltage drop, in automotive applications the L4947/L4947R can work correctly even during the cranking phase, when the battery voltage BLOCK DIAGRAM Pentawatt ORDERING NUMBERS: L4947 L4947R could fall as low as 6V.
