LOW DROPOUT VOLTAGE REGULATOR
ꢀ GENERAL DESCRIPTION
ꢀ PACKAGE OUTLINE
The NJM2867/68 is a 100mA output low dropout voltage
regulator with ON/OFF control.
Advanced Bipolar technology achieves low noise, high ripple
rejection and low quiescent current.
Small packaging, 0.1µF small decoupling capacitor, built-in noise
bypass capacitor make the NJM2865/66 suitable for space
conscious applications.
