About this manual

The L79Lxx series of three-terminal negative regulators are designed for local or on-card regulation to eliminate noise and distribution problems associated with single-point regulation. These devices employ internal current limiting and thermal shutdown, making them robust for a wide range of applications. They are available in SOT-89, TO-92, and SO-8 packages and require no external components for basic operation.
