DESCRIPTION
The L7800A series of three terminal positive
regulators is available in TO-220, TO-220FP,
TO-220FM and D
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
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
