Thanks for reviewing! I will prepare version 2 shortly.

Ok. I added this since the voltage I use for reference is behind a level-shifter,
meaning there is actually no regulator on the board providing that exact
voltage level. Not sure what you mean with "the fixed-voltage-regulator", but
maybe that is what I am looking for in my case?
