NJM2847 Datasheet, PDF (1/4 Pages) New Japan Radio – Very Low Output Voltage Series Regulator

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.
