5v Regulator

5v volt regulator circuit which can be made from only three components, its simple, cheap and easy way to get a current up to 1A and a voltage of more than 5v can only be regulated by this circuit, this circuit can be used as a bread board power supply

1.............. L7805

heat sink ( a small aluminium plate from scrap)

1...............10uf 25v (electrolytic capacitor)

1................1uf 25v(electrolytic capacitor)

green LED (optional)

1k resistor(brown black red) (optional)

soldering iron

wires

common circuit board

this is the circuit diagram of the regulator, i have added a green led in series with the 1k resistor to know whether the circuit is working, (the part is optional ) a voltage between 7v to 15v 1A current  can be given as the input.

assemble the transistor and the capacitors according to the circuit diagram in a common circuit board 

most of the mistakes are formed due to poor soldering and the mistake in connecting diodes. always double check the capacitors are connected in forward bias since it explodes when reverse biased in case of electrolytic capacitor
hope this circuit will be used by the members, and if so i will bring more circuits
