Programming Voltage Common to the Minus Output
Figure 4
The output will always be the same or less than the programming voltage.
The M/S2 switch must be in the down position. For best results, place a 0.1μF capacitor in parallel with R2.
Vin = (R1R2) / R2 x Vout
Vout = R2 / R1+R2) x Vin
Where Vout is the power supply output voltage. Vin is the programming voltage.
R1 and R2 should be in the 1KΩ to 100KΩ range.
