LM7805 5V Positive Voltage Regulator

The LM7805 is one of the most widely used positive voltage regulators in electronics, converting a higher, less stable input voltage into a clean, regulated 5V output with around 2% regulation accuracy. It is a staple component in countless power supply designs, from simple hobbyist projects to more involved microcontroller-based builds.

With roughly a 2.5V linear drop-out, the regulator needs at least 7V at the input to reliably deliver a clean 5V output, dissipating the difference as heat, so pairing it with a heatsink is recommended for sustained loads. Housed in the TO-220 package with three terminals, it can handle up to 1A of continuous current and is commonly used for regulated power supplies, current limiting, and providing steady 5V power to microcontrollers, sensors, and other electronic appliances.
