KA7810AETU  

Linear & Switching Voltage Regulators

KA7810AETU Description

The KA7810AETU is a linear voltage regulator designed by onsemi, offering a fixed output voltage of 10V and a maximum output current of 1A. This regulator is housed in a TO220-3 package, making it suitable for through-hole mounting. It features a maximum input voltage of 35V and a dropout voltage of 2V at 1A, ensuring efficient operation even under varying input conditions. With a quiescent current of 6 mA and a power supply rejection ratio (PSRR) of 62dB at 120Hz, the KA7810AETU provides stable and reliable regulation. The device operates within a temperature range of 0°C to 125°C, making it suitable for a wide range of industrial and consumer applications. It also includes over-temperature and short-circuit protection features, enhancing its robustness and reliability. Despite being marked as obsolete, the KA7810AETU remains unaffected by REACH regulations and is available in a tube package.
