78XX and 79XX stabilizer with Desain Mini PCB

Circuit Skema Rangkaian - The stabilizer circuit of the IC 78XX and 79XX commonly used for voltage stabilization with a mini PCB design , and practical. In the picture above is looking from top the PCB, with a width of 2 cm and 5 cm height. For input voltage can be directly through the AC because i've put it four rectifier diodes are then forwarded to the Elco and IC , that has a stable output in accordance with IC series. What if the IC series 7805 and 7905 , the output voltage of 5 Volts. If the series IC 7812 and 7912 then the output voltage of 12 volts , and so on.
