This circuit is most commonly used in 5Volt DC Regulator, Here IC7805 is used as a reulator due to its regulating characteristics this circuit provides constant 5 Volt DC output. Bridge rectifier consists of four 1N4001 diode and then 100uF capacitor filters large size ac ripples.
Un regulated DC voltage range from 8 volt to 12 volt is applied to the IC7805 regulator. In this IC pin 1 is considered as input and pin 2 falls on ground then pin 3 gives regulated output. At the ouput pin 0.1 uF capacitor is connected for to remove small sized ac ripples from regulated DC output. Finally at the ouput you will get regulated 5 Volt DC.
