NJRC NJM2867F28 Low dropout voltage regulator Datasheet

NJM2867/68
LOW DROPOUT VOLTAGE REGULATOR
GENERAL DESCRIPTION
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.
