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
Component list
7805 regulator IC
100 uF electrolytic capacitor, at least 25V voltage rating
10 uF electrolytic capacitor, at least 6V voltage rating
100 nF ceramic or polyester capacitor
