The L7800 series of positive voltage regulators has an output current of up to 1.5A and output voltages of 5V, 5.2V, 6V, 8V, 8.5V, 9V, 12V, 15V, 18V, and 24V. It features thermal overload protection, short circuit protection, and output transition safe area protection.
The L7800 series are three‑terminal positive voltage regulators offered in TO‑220 ISOWATT220, TO‑3 and DPAK packages. They provide fixed output voltages ranging from 5 V to 24 V and can deliver up to 1.5 A of output current when adequate heat sinking is used. Internal current limiting, thermal shutdown and safe‑area protection make the devices highly robust.
The document includes absolute maximum ratings, thermal data, ordering numbers, application circuits, detailed electrical characteristics for each voltage version, mechanical dimensions for the DPAK package, and legal disclaimer information.
