GENERAL DESCRIPTION
This Series of fixed-voltage monolithic 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 100 mA of output current. The inter-
nal limiting and thermal shutdown features of
these regulators male them essentially immune
to overload. When used as a replacement for a
zener diode-resistor combination, an effective
improvement in output impedance can be obtain
-ed together with lower-bias current.
