NJM2893 Series
3Output Low Dropout Voltage Regulator

Download Datasheet

  • Description

    The NJM2893 is a 3-channel low dropout voltage regulator featuring a low noise, high precision of ±1.0%, high ripple rejection ratio of 75dB, and 100mA output current (all outputs).It has an ON/OFF function which reduces the quiescent current on stand-by mode. Further the NJM2893 is available in a small and thin surface mount 8-lead MSOP (TVSP) package, and it can use ceramic capacitor of 1µF as an output capacitor. Therefore it can achieve a high-density mounting and is suitable for small precision devices, portable devices and others.
