Description
L78xx, L78xxC
L78xxAB, L78xxAC
Positive voltage regulator ICs
Datasheet − production data
TO-220
TO-220FP
The L78xx series of three-terminal positive
regulators is available in TO-220, TO-220FP, TO3, 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 shutdown 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.
