KA7909TU General Description

For a fixed -9V output voltage, the KA7909TU is the ideal choice for reliable voltage regulation. As part of the 78xx series of voltage regulators, this IC is designed to provide a stable and consistent voltage output for your electronic circuits. With a maximum output current of 1A and a dropout voltage of 2V, the KA7909TU ensures reliable performance even under varying load conditions. Its built-in thermal overload protection circuit offers added peace of mind, preventing the IC from overheating and potentially damaging your circuit. In addition, the KA7909TU requires two external capacitors for stability and noise filtering, making it a comprehensive solution for your voltage regulation needs. Housed in a TO-220 package, this IC is easy to mount on a heat sink for improved heat dissipation and long-term reliability
