DESCRIPTION
The L7800A series of three terminal positive
regulators is available in TO-220, TO-220FP,
TO-220FM 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 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
TO-220
TO-220FP
TO-220FM
D2PAK
devices can be used with external components to
obtain adjustable voltage and currents.
