and temperature

DESCRIPTION

The EZ1585 series of high performance positive

voltage regulators are designed for use in applications

requiring low dropout performance at full rated

current. 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. The EZ1585 series

are three terminal regulators with fixed and adjustable

voltage options available in popular packages.
