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, 0.1F small decoupling capacitor, built-in noise bypass capacitor make the NJM2865/66 suitable for space conscious applications. PACKAGE OUTLINE
