The KIA7810API-U/PF is a linear voltage regulator manufactured by KEC. It is constructed in a TO-220F (TO-220IS) RoHS package, which includes a 3-terminal voltage regulator IC, mounted to a metal and plastic heatsink. This specific IC is designed to provide a fixed output voltage of 5V, up to 1A of output current, with a maximum input voltage of up to 35V. The KIA7810API has short circuit protection, and is capable of thermal shutdown, as well as current limiting. The device is designed for use in applications such as embedded systems, communication systems, and other portable devices where linear voltage regulation is necessary.
