Circuit adjustable power supply LM7805. 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.
