Low Dropout Voltage Regulator
NJM2878
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), 0.47µF small decoupling
capacitor and built-in noise bypass capacitor make the NJM2878
suitable for space conscious applications.
