NJM2868F

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. PACKAGE OUTLINE NJM2867F3 NJM2867F/NJM2868F FEATURES High Ripple Rejection 75dB typ. (f=1kHz Vo=3V Version) Output Noise Voltage Vno=40µVrms typ. Output capacitor with 0.1µF ceramic capacitor (Vo≥2.8V) Output Current Io(max.)=100mA High Precision Output Vo±1.0% Low Dropout Voltage 0.10V typ.
