STMicroelectronics L7800AB/AC Series Precision 1A Regulators Handbook
The L7800AB/AC series are three‑terminal positive linear regulators offered in TO‑220 and DPAK packages with fixed output voltages of 5 V, 6 V, 8 V, 9 V, 12 V, 15 V, 18 V, 20 V and 24 V. They provide up to 1 A output current, internal current limiting, thermal shutdown and safe‑area protection, making them robust for a wide range of applications.
The document includes absolute maximum ratings, thermal resistance data, electrical characteristics for each voltage version, mechanical dimensions for the DPAK package, and ordering information. It also contains typical application circuits, test setups, and regulatory notices.
