General Description
This 78Lxx series are fixed-voltage
monolithic
Features
3-Terminal Regulators
Output Current Up to 100 mA
Internal Thermal Overload Protection
Internal Short-Circuit Limiting
integrated-circuit voltage regulators are designed for
a wide range of applications. These applications
include on-card
regulation
for elimination
of
noise and distribution
problems
associated with
can
to
be
single-point regulation. In addition, they
used
with
power-pass
elements
make
high-current voltage regulators. Each
of these
regulators can deliver up to 100 mA of output current.
The internal
limiting and termal shutdown
Application
Linear Regulator
Graphic Card
Adapter
Charger
Consumer Electronics
features of these regulators make them essentially
immune to overload.
