12V, 10A Regulated Power Supply

This is 12V 10A regulated Power supply circuit with PCB Layout. We use LM723 HIGH PRECISION VOLTAGE REGULATOR and 2N3055 power NPN transistor as main parts. The two 2N3055 x 2 to increase current up form LM723. We need to use 10A transformer, the power transistors to hold Heat-sink. In circuit, we can adjust easily the output voltage with VR1 – 1K.

12V, 10A Regulated Power Supply Using IC 723+2N3055


12V 10 amp power supply circuit using LM723 and 2N3055

My friend wants the 12V Power supply for High Current 10A load. I tries to search see meet this circuit will is appropriate. Because of use IC-LM723. It is the integrated circuit Voltage Regulator at good one although older already. But still be usable well. Fine decorate voltage output with well. Besides still have the transistor 2N3055 numbers are highly popular transistor again the one number. Make all equipment of this circuit seeks easy certainly. If friends want to give 10A electric tall currents. Should use a pot transforms the sky that has 10A sizes with. For VR1 give for fine decorate voltage output get as well be can fine about 0-16V.  Or 13.8 volts 10A  The detail is other , please see in the circuit better.
