com 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.
