The KA7805A is a three-terminal positive voltage regulator manufactured by On Semiconductor. It is designed for a wide range of applications requiring a stable 5V output. The device is housed in a TO-220AB package, suitable for through-hole mounting.
Key electrical specifications include a minimum input voltage of 7.5V and a maximum input voltage of 25V. It provides a fixed output voltage of 5V with an accuracy of 2%. The regulator can deliver up to 1A of output current and has a typical dropout voltage of 2V. Its quiescent current is typically 6mA, and it offers a Power Supply Rejection Ratio (PSRR) of 68dB.
Thermal considerations are important for this component, with a minimum operating temperature of 0°C and a maximum operating temperature of 125°C. The KA7805A series incorporates internal current limiting, thermal shut down, and safe operating area protection, making it a robust choice for various electronic designs.
This voltage regulator is useful in applications such as power supplies, on-card regulation, and general-purpose voltage regulation where a reliable 5V source is needed.
