NJM2386/88
LOW DROPOUT VOLTAGE REGULATOR WITH ON/OFF CONTROL
GENERAL DESCRIPTION
The NJM2386/88 is a general purpose low dropout voltage
regulators with ON/OFF control.
The output current is up to 1.0A and dropout voltage is 0.2V
typical at 500mA load.
It features high maximum input voltage of 35V for a wide
application range including TV, home appliances and power
modules.
