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 NJM2370U1 NJM2370R/RB1 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.
