DESCRIPTION
The EZ1084 series of high performance positive
voltage regulators are designed for use in applications
requiring low dropout performance at full rated current.
Additionally, the EZ1084 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. The EZ1084 has both fixed and
adjustable voltage options, while the EZ1084B is
adjustable only for cost sensitive applications. These
devices are available in the popular TO-220 and TO-
263 packages.
