Japan Radio Corporation  

NJM2387A

ADJUSTABLE LOW DROPOUT VOLTAGE REGULATOR

WITH ON/OFF CONTROL

GENERAL DESCRIPTION

The NJM2387A is an adjustable low dropout voltage regulator.

The output current is up to 1.0A and dropout voltage is 0.2V typ. at

Io=0.5A.

OFF control quiescent current is drastically reduced compare with

the current NJM2387 through changing ON/OFF control circuit.

The NJM2387A is suitable for power module, TV, Display, car stereo

and low power applications.
