6-12V VARIABLE REGULATED POWER SUPPLY CIRCUIT SCHEMATIC DIAGRAM

Notes:

  • C1 filters the noise and spikes off the AC. If you find the circuit output too noisy add another electrolytic capacitor over the output terminals. Value can be between 10 and 100uF/25V.
  • The output voltage is variable with the 10K-potentiometer.
  • The transformer input voltage refer to your home power source.
