Description
The L78xx series of three-terminal positive
regulators is available in TO-220, TO-220FP,
TO-3, D2PAK and DPAK 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 current
limiting, thermal shut-down and safe area
protection, making it essentially indestructible. If
adequate heat sinking is provided, they can
deliver over 1 A output current. Although designed
primarily as fixed voltage regulators, these
devices can be used with external components to
obtain adjustable voltage and currents.
