Description
The ARX series of low noise DC
voltage regulators is a new line of ultra
highly reliable microcircuits designed for
military and aerospace applications.
These regulators utilize advanced
multichip module design techniques to
provide state-of-the-art performance
features with no sacrifice in reliability.
The ARX series regulators can be
used in applications where minimum size
and maximum output power is required.
These regulators are designed to operate
over the full military operating case
temperature range of -55C to +125C.
Outstanding high frequency ripple
rejection, input overshoot rejection and
input noise rejection are features of the
ARX series that are not available from
monolithic regulators.
To provide protection against output
overloads, current limiting and reduced
current foldback short circuit protection
are standard.
