NJM2801

PRELIMINARY

Low Dropout Voltage Regulator with Reset

The NJM2801 is a low dropout voltage regulator with

reset function.

It provides up to 150mA of logic supply, and the reset

function monitors either input or output voltage of the

regulator with 2% accuracy.

It is suitable for local power supply and reset for small

micro controller and other logic chips.
