The L7805 Voltage Regulator is a fixed 5V linear regulator IC from the 78xx series, designed to provide a stable and regulated +5V DC output from an unregulated DC input (typically ranging between 7V to 35V). With its 3-pin configuration (Input, Ground, Output), it offers a simple and reliable solution for powering 5V logic circuits, microcontrollers, and other low-voltage devices.
The regulator can supply up to 1A of continuous current (with appropriate heat sinking), making it suitable for a wide range of small to medium power applications. The L7805 includes built-in protection features, such as thermal shutdown, current limiting, and short-circuit protection, ensuring safe and reliable operation under various load conditions.
Thanks to its ease of use, low cost, and dependable performance, the L7805 is a standard choice in power supply designs, especially in DIY electronics, embedded systems, and educational projects.
