Output Voltage Configuration Method

Please connect resistors R1 and R2 (which determines the output voltage) as shown in Fig.14.

Please be aware that the offset due to the current that flows from the ADJ terminal becomes large when resistors with large

values are used. The use of resistors with R1=5kΩ to 10kΩ is recommended.

Vo ≒ ADJ × (R1+R2) / R1
