The L7805 Voltage Regulator IC is a three-terminal positive linear voltage regulator designed to provide a stable 5V DC output from a higher DC input voltage. It is widely used in electronic circuits that require a regulated 5V supply for microcontrollers, sensors, digital logic, and other electronic components.
Featuring built-in thermal overload protection, short-circuit protection, and safe operating area protection, the L7805 is suitable for power regulation in DIY electronics, embedded systems, and industrial control circuits. It is available in package variants such as TO-220, depending on the manufacturer and specific model.
