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 f ixed output voltages, making it useful i n a
wide range of applications. These regulators can
provide local on-card regulation, eliminating the
distribution proble ms 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 ou tput current. Although des ign ed
primarily as fixed voltage regulators, these
dev ices c an b e us ed with ex ternal c om ponents t o
obtain adjust able voltage and currents.
