Basically I need to take the wall voltage and provide 3.3 V, 12V, and 30 V DC voltages to power various components in my project. I decided to use a 12 V DC wall wart to convert the wall AC to DC.
I already got the 3.3 V and 30 V done using a boost converter and a regulator, but now I am stuck on the 12 v.
I measured the wall wart open circuit, and it is ~12.3 V. I am using the 12 V to provide voltage rails for an op amp, as well as bias a photodiode. My question is do I need to use a circuit to regulate this 12 v from the wall wart, or is a wall wart stable enough? Is there a simple transistor or Zener diode circuit that can be used to provide some power surge protection or something? So far I haven't been able to find any 12 v in 12 v out voltage regulators
