The EZ1085 series of high performance positive voltage
regulators are designed for use in applications requiring
low dropout performance at up to 3A. Additionally, the
EZ1085 series provides excellent regulation over
variations in line, load and temperature.
Outstanding features include low dropout performance
at rated current, fast transient response, internal
current limiting and thermal shutdown protection of the
output device.
A variety of options are available for maximum flexibility:
the EZ1085C has both fixed and adjustable voltage
options and is designed for use in commercial applica-
tions and the EZ1085I is adjustable only for industrial
applications.
All devices are available in the popular TO-220 and
TO-263 packages.
