NCV4949C

100 mA, 5.0 V, Low Dropout

Voltage Regulator with

Reset and Sense

The NCV4949C is a monolithic integrated 5.0 V voltage regulator

with a very low dropout and additional functions such as reset and an

uncommitted voltage sense comparator.

www.onsemi.com

It is designed for supplying microcontroller/microprocessor

controlled systems particularly in automotive applications. The

NCV4949C has improved reset behavior for lower input and output

voltage levels.
