The L7800 series of three-terminal positive regulators is available inTO-220, TO-220FP, TO-3 and D2PAK packages and several fixed outputvoltages, making it useful in a wide range of applications.
These regulators can provide local on-card regulation, eliminating thedistribution problems associated with single point regulation.
Each type employs internal current limiting, thermal shut-down and safearea protection, making it essentially indestructible.
If adequate heat sinking is provided, they can deliver over 1A outputcurrent.
Although designed primarily as fixed voltage regulators, these devicescan be used with external components to obtain adjustable voltage andcurrents.
