DESCRIPTION

The EZ1083 series of high performance positive

voltage regulators are designed for use in applications

requiring low dropout performance at full rated current.

Additionally, the EZ1083 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 EZ1083 has both fixed and

adjustable voltage options, while the EZ1083B is

adjustable only for cost sensitive applications. These

devices are available in the popular TO-220 package.
