The L7800 series is a three-terminal positive regulator with an output current of up to 1.5A and multiple output voltage options. It features thermal overload protection, short circuit protection, and output transition SOA protection.
The L7800 series are three‑terminal positive voltage regulators offered in TO‑220, TO‑220FP, TO‑220FM, TO‑3 and DPAK packages. They provide fixed output voltages from 5 V to 24 V and can deliver up to 1.5 A when proper heat sinking is used. Internal current limiting, thermal shutdown and safe‑area protection make the devices robust for a wide range of applications.
The document includes absolute maximum ratings, thermal data, connection diagrams, order codes, example application circuits and detailed electrical characteristics for each fixed‑output version such as L7805, L7806, L7808, L7812, L7815, L7818 and L7820.
