NJM2370
LOW DROPOUT VOLTAGE REGULATOR WITH ON/OFF CONTROL
■ GENERAL DESCRIPTION
The NJM2370 is a low dropout voltage regulator with
ON/OFF control.
■ PACKAGE OUTLINE
It features dropout voltage of 0.1V at IO=30mA, low
output noise and high ripple rejection by connecting an
external capacitor to noise bypass terminal.
It’s suitable for portable items such as cellular phones,
video camera and others.

■ 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.
