NJM2800
PRELIMINARY Low Dropout Voltage
Regulator with Reset ■ GENERAL DISCRIPTION
The NJM2800 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.
