Overview
The L79L05ACD13TR is a part of the L79L series of three-terminal negative voltage regulators produced by STMicroelectronics. These regulators are designed to provide a fixed negative output voltage and are known for their robustness, featuring internal current limiting and thermal shutdown, making them essentially indestructible. With adequate heat-sinking, they can deliver up to 100 mA of output current. This component is ideal for applications requiring local or on-card regulation to eliminate noise and distribution problems associated with single-point regulation.
