NJM2370 LOW DROPOUT VOLTAGE REGULATOR WITH ON/OFF CONTROL GENERAL DESCRIPTION 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 capacitance value. The NJM2370 is available in a small 5-lead SOT-89 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, PHS and movie camera.

TEST CIRCUIT -2- Ver.2012-07-18 NJM2370 TYPICAL APPLICATION (1) In Nonuse of ON / OFF Control Connect control terminal (1Pin) to VIN terminal (5Pin) When a resistance "R" is connected, the quiescent current decreases, but minimum operating voltage increases. Please refer to a figure of Output Voltage vs. Control Voltage. (2) In Use of ON / OFF CONTROL When the control terminal is "H", it is ON. When the control terminal is "L" or "open", it is OFF. *Noise bypass Capacitance Cp Noise bypass capacitance CP reduces noise generated by band-gap reference circuit. Noise level and ripple rejection will be improved when larger CP is used. Please refer to the typical characteristics to determine the value. Use of smaller CP value may induce oscillation. Please make sure to use CP value of greater than 0.1uF to avoid the problem.
