NJM2815 Series
1.0A Low Dropout Regulator with Voltage Correction Circuit

Download Datasheet

  • Description

    The NJM2815 is a low dropout regulator with an internal voltage correction circuit which delivers up to 1.0 A of output current. The voltage correction (cable drop compensation) raises the output voltage in proportion to the load current. This function corrects the voltage drop due to cable or writing board resistance. Unique features, such as overcurrent protection, thermal shutdown, soft-start and error flag output make the NJM2815 ideal for portable devices charged with USB cable.
