NJM2888
LOW DROPOUT VOLTAGE REGULATOR
GENERAL DESCRIPTION
The NJM2888 is a low dropout voltage regulator with ON/OFF
control.
Advanced Bipolar technology achieves low noise, high ripple
rejection and low quiescent current.
Small packaging, 1.0µF small decoupling capacitor and built-in
noise bypass capacitor less make the NJM2888 suitable for space
conscious applications.

Input Capacitance C
IN
Input Capacitance C
IN
is required to prevent oscillation and reduce power supply ripple for applications with high
power supply impedance or a long power supply line.
Use the C
IN
value of 0.1µF greater to avoid the problem.
C
IN
should connect between GND and V
IN
as short as possible.
In the case of using a resistance "R" between V
IN
and control.
The current flow into the control terminal while the IC is ON state (I
CONT
) can be reduced when a pull up resistance
"R" is inserted between V
IN
and the control terminal.
The minimum control voltage for ON state (V
CONT (ON)
) is increased due to the voltage drop caused by I
CONT
and the
resistance "R". The I
CONT
is temperature dependence as shown in the "Control Current vs. Temperature"
characteristics. Therefore, the resistance "R" should be carefully selected to ensure the control voltage exceeds the
V
CONT (ON)
over the required temperature range.
