Please open the terminal V.ADJ when you use the output voltage with

rating, without changing. By connecting resistance between the terminal

+Vout (9~11Pin) and V.ADJ (12 Pin), or between the terminal V.ADJ (12 pin)

and GND (5~8 pin) you can change output voltage within the range of

voltage in Table 1. Please refer to the undermentioned equation

for the calculation of external resistance. Please confirm the output

voltage and adjust resistance value after calculating external resistance.

you can change output voltage within the range of voltage in Table 1.

To reduce the output voltage

Rx×Ry×(Vo-Vref)

VR1 Rx×2.45-Ry(Vo-Vref)

VR2 = OPEN

To add the output voltage

Vref×Rx×Ry

VR2 = Ry(Vo-Vref)-Vref×Rx
