12.6V voltage regulator using PNP emitter follower

Today we come to see 12.6V Voltage Regulator Circuit. That use PNP Transistor be main electronic part. By it very the circuit in the character emitter follower or voltage follower make have high current about 0.7 Amp. The part that perform be formed fix voltage output are ZD1 and ZD2, from the circuit notes 6V bilateral. The capacitor C-2200uF help give the circuit has the stability increasingly. For other detail see in a picture.

12V linear regulator for Transceiver Radio

This circuit is 12V linear regulator for the receiver radios model transistor. which with regard to often use current the very. Especially when do signalling . The 2N3055 transistors that use in place circuit s pay electric this power. Then must pay the electric current has very much. For a resister R1 in the circuit will perform to decrease the quantity will of the electric power to will lose to go to down and make can use cheap transistor get . And in value filtration R1. As a result have Voltage fall straddle all about 2 Volt. The Zener Diode use 12.7V values or 12.6V 1Watt. This circuit size builds easy then convenient for friends. At a novice and seek easy equipment certainly. And still can pay the electric current has about 2 Amp. Request to have fun 12V linear regulator for Transceiver Radio circuits please sir.

Switching supply computer 5V 15A 12V

Today I leads Switching supply computer Circuit. Come to give friends in see again. By this circuit has can to give electricity pressure 5V 15A,-5V 1A,12V 10A,-12V 1A and have can to give the electric power about 200W. I hope that this circuit may in rows checking meditation repairs a computer has of friends. By think use the integrated circuit number TL494 again. And still use the transistor power as well. May repair not difficult be lucky sir.
