CIN: Input capacitor (22µF or larger)
CO: Output capacitor (47µF or larger)
R1, R2: Output voltage setting resistors
The output voltage can be adjusted by connecting R1 and R2 as shown
If a low ESR capacitor (such as a ceramic capacitor) is used
for the output capacitor, oscillation may occur.
above.
The recommended value for R2 is 10kΩ.
R1=(VO–VADJ)÷(VADJ/R2)
*1. D1: Reverse bias protection diode
This diode is required for protection against reverse
biasing between the input and output.
(Sanken RU2Z is recommended.)
*2: Insert R3 in case of setting VO to VO ≤ 1.5V.
The recommended value for R3 is 10kΩ.
