NJM2386/88

LOW DROPOUT VOLTAGE REGULATOR WITH ON/OFF CONTROL

GENERAL DESCRIPTION PACKAGE OUTLINE

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. NJM2386DL3 NJM2388F
