L79L05ACUTR Description

Short technical summary and product information.

The STMicroelectronics L79L05ACUTR is a three-terminal negative voltage regulator with an output voltage of -5V. It is capable of delivering up to 100mA of output current, provided adequate heat-sinking is employed. This regulator series features internal current limiting and thermal shutdown, making it highly robust against overloads.

 

Designed for local or on-card regulation, the L79L05ACUTR helps eliminate noise and distribution problems associated with single-point regulation. It can also be used with power pass elements to create high-current voltage regulators. The device offers protection against thermal overload and short-circuit conditions.

 

The L79L05ACUTR is supplied in a SOT-89-3 surface-mount package. Its operating temperature range is from 0°C to 125°C. The regulator requires no external components for its basic operation, simplifying circuit design.
