Very Low Output Voltage Series Regulator

Japan Radio Corporation  

NJM2847

Very Low Output Voltage Series Regulator

GENERAL DESCRIPTION

The NJM2847 is a series voltage regulator that delivers up to

150mA output current with the output voltage of 0.8 to 1.4V with

ON/OFF control.

Advanced Bipolar technology achieves low noise, high ripple rejection,

High accuracy and low quiescent current.

Small packaging and 2.2µF small decoupling capacitor make

the NJM2847 suitable for space conscious applications.
