If a low ESR capacitor (such as a ceramic capacitor) is used
for the output capacitor, oscillation may occur.
*1. D1: Reverse bias protection diode
This diode is required for protection against reverse
biasing between the input and output.
(Sanken RU2Z is recommended.)
R1, R2: Output voltage setting resistors
The output voltage can be adjusted by connecting R1 and R2 as shown
above.
The recommended value for R2 is 10kΩ.
