DESCRIPTION
The L4925 is a monolithic integrated 5V voltage
regulatorwith a very low dropout output and addi-
tional functions such as power-on reset and pro-
grammable reset delay time. It is designed for
supplying microcomputer controlled systems es-
pecially in automotiveapplications.
This is advancedinformation on a new product now in development or undergoing evaluation. Details are subject to change without notice.
