L79L09ACUTR Description

Short technical summary and product information.

The STMicroelectronics L79L09ACUTR is a three-terminal negative voltage regulator designed for a wide range of applications. It offers a fixed -9V output voltage and can deliver up to 100 mA of output current. The device incorporates internal current limiting and thermal shutdown, making it highly reliable.

 

Key electrical characteristics include a typical quiescent current of 5.5 mA and a PSRR of 44dB at 120Hz. The operating temperature range is from 0°C to 125°C, and it is protected against over-temperature and short-circuit conditions.

 

This regulator is available in a surface-mount SOT-89-3 package, also known as TO-243AA. Its design eliminates the need for external components, simplifying circuit design and reducing board space. It is suitable for local or on-card regulation to eliminate noise and distribution problems associated with single-point regulation.
