NJM2887
! TYPICAL APPLICATION
1 In the case where ON/OFF Control is not required:
VIN
VIN
VO
0.33µF
NJM2887
R
(0~300kΩ)
CONTROL
VADJ
GND
VO
2.2µF
OR
R1
4.7µF(Vo≤2.6V)
R2
100kΩ
Connect control terminal to VIN terminal
The quiescent current can be reduced by using a resistance “R”. Instead, it increases the minimum operating voltage.
For further information, please refer to Figure “Output Voltage vs. Control Voltage”.
2 In use of ON/OFF CONTROL:
