Description
This series of fixed-voltage integrated-circuit
voltage regulators is designed for a wide
range of applications. These applications
include on-card regulation for elimination of
noise and distribution problems associated
with single-point regulation. In addition, they
can be used with power-pass elements to
make high-current voltage regulators. One of
these regulators can deliver up to 100mA of
output current. The internal limiting and
thermal-shutdown
features of these
regulators make them essentially immune to
overload. When used as a replacement for a
zener diode-resistor combination, an
effective improvement in output impedance
can be obtained, together with lower bias
current.
