DESCRIPTION
The L78M00 series of three-terminal positive
regulators is available in TO-220, TO-220FP,
SOT-82, SOT-194 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 0.5A output current. Although
designed primarily as fixed voltage regulators,
these devices can be used with external
components to obtain adjustable voltages and
currents.
