■ 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.
