Description
The L7800A series of three terminal positive
regulators is available in TO-220, TO-220FP, and
D
2
PAK 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
problem 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 adjustable voltage and currents.
