Very Low Output Voltage Series Regulator

Download Datasheet

  • Description

    The NJM2847 is a series voltage regulator that delivers up to 150mA output current with the output voltage of 0.8 to 1.4V with ON/OFF control. Advanced Bipolar technology achieves low noise, high ripple rejection, High accuracy and low quiescent current. Small packaging and 2.2µF small decoupling capacitor make the NJM2847 suitable for space conscious applications.
