The L7800 series of three-terminal positive regulators is available in TO-220 ISOWATT220 TO-3 and D2PAK packages and several fixed output voltages, making it useful in a wide range of applications.Theseregulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustablevoltages and currents.
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 be used for on‑card regulation, eliminating distribution problems of single‑point regulation.
Each device includes internal current limiting, thermal shutdown, and safe‑area protection, allowing up to 1.5 A of output current when adequate heat‑sinking is provided. The datasheet lists thermal resistance values, dropout voltage, short‑circuit current, and supply‑voltage rejection for each voltage version.
