6V DC Power Supply Schematic-LM317 Circuit
LM317 output voltage of this circuit is 6V DC, source from the stress out of the 12V CT AC transformer, and then converted to DC half-wave voltage by diodes D1-D2, and filtered by C1 condensator. The transformer is used should be about 1-2A.
Output voltage of 6V DC power supply circuit is determined by the value of R1 and R2. Diodes D3-D4 on the LM317 voltage current circuit to protect poor return for LM317 circuit IC. As for the other capacitors C3-C4 is used to refine the output voltage, and complete power supply circuits. See the schematic below:
More information to determine the value of R1 and R2 according to the desired output voltage, please download the datasheet of the LM317 circuit. Do you have an idea for a variable voltage out?. Download LM317 Calculator (Excel Files).
Congratulations experiment with LM317 circuit to one another output voltage and good luck!.
