NCV4949A: Linear Voltage Regulator, LDO, 100 mA, with Reset and Sense

The NCV4949A 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. It is designed for supplying microcontroller/microprocessor controlled systems particularly in automotive applications. The NCV4949A has improved reset behavior for lower input and output voltage levels.
