The EZ1585 series of high performance positive voltage
regulators are designed for use in applications requiring
low dropout performance at up to 4.6A. Additionally, the
EZ1585 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 EZ1585C is intended for commercial applications and
has both fixed and adjustable voltage options; the
EZ1585I is intended for industrial applications and is
adjustable only.
All devices are available in the popular TO-220 and
TO-263 packages.
