NJM2370 LOW DROPOUT VOLTAGE REGULATOR WITH ON/OFF CONTROL GENERAL DESCRIPTION PACKAGE OUTLINE The NJM2370 is a low dropout voltage regulator with ON/OFF control. It features dropout voltage of 0.1V at I =30mA, low O output noise and high ripple rejection by connecting an NJM2730U NJM2730R external capacitor to noise bypass terminal. Its suitable for portable items such as cellular phones, video camera and others. FEATURES Output Current (150mA min. (V -0.3V)) O Low Dropout Voltage (0.1V typ.
