NJM2386A
LOW DROPOUT VOLTAGE REGULATOR WITH ON/OFF CONTROL
ꢀ GENERAL DESCRIPTION
ꢀ PACKAGE OUTLINE
The NJM2386A is a general purpose low dropout voltage regulators
with ON/OFF control.
The output current is up to 1.0A and dropout voltage is up 0.2V
typical at 500mA load.
NJM2386ADL3
It features high maximum input voltage of 30V for a wide application
range including TV, home appliance and power modules.
Compared with the NJM2386, Off control quiescent current is
significantly reduces for current sensitive applications.

Connect control terminal to VIN terminal.
The quiescent current can be reduced by using a resistance “R”. Instead, it increases the minimum operating
voltage. For further information, please refer to Figure “Output Voltage vs. Control Voltage”.
