This project demonstrates how to build a simple Voltage Regulator using the 7805 integrated circuit (IC). The 7805 provides a stable 5V output from a higher input voltage, making it ideal for powering circuits and components that require a 5V power supply.

• Name: 7805 Voltage Regulator
• Type: Linear Voltage Regulator
• Input Voltage: 7V to 35V
• Output Voltage: 5V DC
• Current Output: 1A (typical)

This is a basic, easy-to-understand circuit designed for beginners. It uses the 7805 voltage regulator IC along with capacitors, diodes, and other passive components to ensure a stable output voltage.

Below is the schematic diagram for the 7805 Voltage Regulator.

The 3D PCB model gives you a visual representation of how the circuit board looks in 3D before fabrication.

• Compact design for various applications.
• Efficient voltage regulation with minimal heat dissipation.
• Perfect for powering Arduino, Raspberry Pi, and other 5V electronics.
• Easy-to-understand circuit layout and simple components.

1. Connect a power source to the input terminals (7V-35V DC).
2. The 5V output can be used to power any 5V device (such as Arduino boards).
3. Make sure to use appropriate heat sinks or ensure proper cooling if higher currents are drawn.
4. This board is ready to be used for any project that requires a stable 5V power source.
