DESCRIPTION：
The L7800 series of three-terminal positive regulators is available in TO-220, TO-220FP,TO-220FM,
TO-3 and D2PAK packages and several fixed output voltages, making it useful in a wide range of
applications. These regulators can provide local on-card regulation, eliminating the distribution
problems associated with single point regulation. Each type employs internal currentlimiting, 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 reg-
ulators, these devices can be used with external components to obtain adjustable voltage and currents.
