Power Supply 5V

Circuit diagram of the power supply.
The capacitors must have enough high voltage rating to safely handle the input voltage feed to circuit. The circuit is very easy to build for example into a piece of veroboard.

Pinout of the 7805 regulator IC.
• 1. Unregulated voltage in
• 2. Ground
• 3. Regulated voltage out
