L79L15ABD13TR Description

Short technical summary and product information.

The STMicroelectronics L79L15ABD13TR is a negative voltage regulator from the L79L series, designed for applications requiring stable voltage regulation. This device offers a fixed output voltage of -15V and can deliver an output current of up to 100mA. It incorporates internal current limiting and thermal shutdown features, making it highly reliable and essentially indestructible under normal operating conditions, provided adequate heat sinking is used.

 

Key electrical characteristics include a maximum input voltage of -35V, a quiescent current of 6mA, and a maximum supply current of 6.5mA. Protection features include over-temperature and short-circuit protection, eliminating the need for external components in many applications.

 

The L79L15ABD13TR is supplied in an 8-SOIC surface-mount package, suitable for automated assembly processes. Its design is intended for local voltage regulation, helping to 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.
