Quality Control: Learn More
The onsemi KA7809ETU is a positive fixed 9V linear voltage regulator with a 1A output current capability, housed in a TO-220-3 package. This component is designed for through-hole mounting and offers robust protection against over-temperature and short-circuit conditions. Featuring a typical quiescent current of 8mA and a maximum input voltage of 35V, the KA7809ETU provides a stable output with a dropout voltage of 2V at 1A. Its power supply rejection ratio (PSRR) is 71dB at 120Hz. This regulator finds application in various industrial and consumer electronics, including power supplies, battery chargers, and automotive systems. The device operates across a temperature range of -40°C to 125°C.
