Description
The L78MxxAB series of three-terminal positive
regulators is available in TO-220 and DPAK
packages and with 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 0.5 A output
current. Although designed primarily as fixed
voltage regulators, these devices can be used
TO-220
DPAK
with external components to obtain adjustable
voltage and currents.
