DESCRIPTION
The L4945 is a monolithic integrated circuit in
Versawatt package specially designed to provide
a stabilizedsupply voltage for automotive and in-
dustrial electronic systems. Thanks to their very
low voltage drop, in automotive applications the
devices can work correctly even during the crank-
ing phase, when the battery voltage could fall as
low as 6V. Furthermore, they incorporate a com-
plete range of protection circuits against the dan-
gerous overvoltages always present on the bat-
tery rail of the car.
Thisis advanced information on a new product now in development or undergoing evaluation. Details are subject tochange without notice.
