DESCRIPTION
The L78M00AB series of three-therminal 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 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.
