7805 Voltage Regulator Circuit | 12v to 5v Stepdown Converter

7805 Voltage Regulator Circuit | 12v to 5v Stepdown Converter is a circuit were very simple and it has 2 components only to make it. This circuit can be use a mobile charger it is because it has 5V output.
Components Needed:
- 7805 transistor
- Capacitor 25v and 10v
- Connecting wires
- 6-14v output supply
- USB port
