Adjustable power supply with circuit integrated positive tension regulator 7805
Adjustable power supply with regulator lm317, we already knew, but the idea now is to use a fixed regulator, and to use some tricks so that the source and turn adjustable.
Here it is a basic outline of the circuit of the source with 7805 however adjustable, we not needed a continuous source regulated, a filter capacitor, an integrated 7805 and a kia4558, ready we have our source with 7805 regulated and adjustable for the potentiometer R1.
