Replacing potentiometer on an adjustable voltage regulator


#1

Is it possible to replace the potentiometer on a Pololu Adjustable 9-30V Step-Up Voltage Regulator U3V50AHV with resistors to get a constant 18v output?

We have wiped the pots and they do not adjust the voltage anymore.

Any help would be greatly appreciated.

Hello.

You can remove the potentiometer and replace R5 with a 220K resistor and R6 with a 16.2K resistor to get 17.92v out. If you would like a bunch pre-made this way, please contact us at support@pololu.com.
