Description
The L78 series of three-terminal positive
regulators is available in TO-220, TO-220FP,
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
embeds 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.
