The STMicroelectronics L7809CV-DG is a positive, fixed 9V linear voltage regulator. It is designed to supply as much as 1.5A of output current with built-in thermal shutdown and short-circuit protection features. The device operates with an input voltage up to 35V and features a typical quiescent current of 8mA.
This regulator is suitable for a wide range of applications requiring a stable 9V supply. Its through-hole TO-220 package facilitates easy mounting on printed circuit boards for various electronic designs. The operating temperature range is from 0°C to 125°C, making it robust for many environments.
Key electrical characteristics include a maximum input voltage of 35V and a typical voltage dropout of 2V at 1A. The Power Supply Rejection Ratio (PSRR) is 55dB at 120Hz, indicating good noise filtering capabilities. The fixed output voltage is precisely regulated at 9V.
Designed for reliability, the L7809CV-DG incorporates over-temperature and short-circuit protection. Its through-hole mounting type and TO-220-3 package are standard for many power supply circuits. This component is a reliable choice for applications needing a consistent 9V power source.
