Detailed Description
The 7805 voltage regulator is one of the most commonly used power regulation ICs in electronics. It converts a higher DC input voltage into a stable 5V output, making it ideal for powering logic circuits, microcontrollers, sensors, and digital components.
Thanks to its simple three-pin design (Input, Ground, Output), the 7805 is easy to integrate into both beginner and professional circuits. It includes internal safety features such as current limiting and thermal protection, which help prevent damage during overload or overheating conditions.
The 7805 is widely used in Arduino projects, embedded systems, educational labs, and DIY electronics. When paired with appropriate input and output capacitors and a heatsink (for higher currents), it delivers dependable long-term performance.
