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
