DESCRIPTION
The L78M00 series of three-terminal positive
regulators is available in TO-220, TO-220FP,
DPAK and IPAK packag es and with several fixed
output voltages,making it u se ful 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 int ernal current limiting,
thermal shut-down and safe area protection,
making it essentially indestructible . If adequate
heat sin king is prov ided, they can deliver over
0.5A output current. Althoug h designed primarily
as fixed voltage regulators, these devices can be
used with external components to obtain
adjustable voltage and currents.
