NJM2386A
LOW DROPOUT VOLTAGE REGULATOR WITH ON/OFF CONTROL
GENERAL DESCRIPTION
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.
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.
