DESCRIPTION
The L78M00AB 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
shut-down and safe area protection, making it
essentially indestructible. If adequate heat sinking
is provided, they can deliver over 0.5A output
current. Although designed primarily as fixed
