DC power supply 5V and 12V using 2N3055-LM309

This be DC power supply regulator circuit be simple. That can give voltage come out 12V and 5V by use part base be Transistor 2N3055 and Zener Diode 12V. Make can take volt can reach about 15V maintain one’s position voltage be stable 12V well. And change the integrated circuit LM309 for regulate about 5V for apply to Digital Circuit general get. For C3-0.1uF filter the frequency disturbs all well. For other detail friends see in the circuit please sir.

12V 5A power supply Regulator with LM1084IT-12

The basic car electrical system gives you around 12-13V when the engine is off and 13-14V when it is running. Not good for a computer, so the basic idea is to use a simple voltage regulator which takes an unregulated voltage in and outputs a regulated voltage. The LM1084IT-12 is a 12V, 5A, Low dropout voltage regulator in a TO220 package to which a heatsink will be added. The low dropout feature is nice as the cars supply varies so much.

Regulator 12V 10A by IC 723+2N3055

This is circuit regulator 12V 10A by IC 723+2N3055.
Q 2N3055 x 2 for to increase form IC LM723.
To use transformer 10A, Transistor to Hold Heatsink.
To adjust the output voltage simplyt by VR1 – 1K.

circuit Regulator 12V 10A by IC 723+2N3055

A friend of me wants 12V Power supply for High Current 10A load. Me tries to search see meet this circuit will should is appropriate. Because of use IC LM723. Be 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 the 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. The detail is other , please see in the circuit better.
