Cire) NJM2370 LOW DROPOUT VOLTAGE REGULATOR WITH ON/OFF CONTROL MIGENERALE DESCRIPTION MIPACKAGE OUTLINE The NJM2370 is a low dropout voltage regulator with ON/OFF control. Its dropout voltage is 0.1V at [o=30mA, also it actualizes tow output noise and high ripple rejection in connecting an external capaciter to noise bypass termina]. NJM2370U NJM2370R It's suitable for portable items such as cellular phone, video camera and others. MFEATURES @Output Current (150mA min. (Vo-0. 3V)) @Low Dropout Voltage (0. 1V typ.
