NJM2370 LOW DROPOUT VOLTAGE REGULATOR WITH ON/OFF CONTROL GENERAL DESCRIPTION PACKAGE OUTLINE The NJM2370 is a low dropout positive voltage regulator with ON/OFF control. It has a low quiescent current, output current of 150mA and low dropout voltage of 0.1V (at IO=30mA). Further it can be added an external noise bypass capacitor. It can be improve the characteristics of output noise and ripple rejection by changing the NJM2370R capacitance value. NJM2370U1 (MSOP8 (VSP8)) The NJM2370 is available in a small 5-lead SOT-89 (SOT89-5) package and thin 8-lead MSOP (VSP) and MSOP (TVSP) packages. These performances make it well-suited for battery-powered portable devices such as a mobile phone, NJM2370RB1 PHS and movie camera. (MSOP8 (TVSP8)) FEATURES Output Current (150mA min.
