NJM2878
Low Dropout Voltage Regulator
GENERAL DESCRIPTION
The NJM2878 is a 150mA output low dropout voltage regulator
with ON/OFF control.
Advanced bipolar technology achieves low noise, high ripple
rejection, high accuracy and low quiescent current.
Small packaging (SC-88A/SC82AB) and very small packaging
(ESON4), 0.47µF small decoupling capacitor and built-in noise
bypass capacitor make the NJM2878 suitable for space conscious
applications.
