7805 Regulator Based power supply

HI Friends,Now We make a power supply for PIC microcontrollers using 7805 regulator.for making power supply we need some components given blow.

                    1.General purpose PCB.
                    2.Transformer (center tap) 12-0-12.
                    3.2 Diode 1N4007.
                    4.Regulator 7805.
                    5.Capacitor (220uF ,0 . 01 uF )

CIRCUIT DIAGRAM OF POWER SUPPLY

working:- 

The Transformer and rectifier circuit give output 12V DC and than the regulator 7805 ( i/p 7-24V, o/p is 5V) give output 5V. now we can use this circuit as power supply for micontroller.
