NJM2878

NJM2878 www.DataSheet4U.com 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), 0.47µF small decoupling capacitor and built-in noise bypass capacitor make the NJM2878 suitable for space conscious applications. PACKAGE OUTLINE NJM2878F3 NJM2878F4 FEATURES High Ripple Rejection 75dB typ. (f=1kHz Vo=3V version) Output Noise Voltage Vno=45µVrms typ. Output Current Io(max.)=150mA High Precision Output Vo ±1.0% Output capacitor with 0.47µF ceramic capacitor(Vo≥2.7V Version) Low Dropout Voltage 0.10V typ.
