Simple power supply

This circuit is very useful in beginners circuits, since most will work on 5v, which is the voltage of this easy little circuit.

How it works:

This circuit is just an implementation of the 7805 integrated voltage regulator. What this little component does is to lower a voltage and stabilize it by reducing noise and ripple, in order for circuits to have the constant voltage needed to work correctly
