DESCRIPTION
The L78M00 series of three-terminal positive
regulators is available in TO-220, TO-220FP,
DPAK and IPAK 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
0.5A output current. Although designed primarily
as fixed voltage regulators, these devices can be
