Output Voltage Adjust
The resistor value for an adjusted output voltage is
calculated by using the following equations:
Output Voltage Adjust Upwards, Increase:
R
kOhm
Output Voltage Adjust Downwards, Decrease:
R
Eg Increase 4% =>V
5 .11 [3 .3(100+4)/(1 .225x4)-(100+2x4)/4=219 .9 kOhm
Eg Decrease 2% =>V
5 .11 x(100/2-2)=245 .3 kOhm
