DESCRIPTION
The EZ1588 series of high performance positive
voltage regulators are designed for use in applications
requiring low dropout performance at full rated current.
Additionally, the EZ1588 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 EZ1588 series are three terminal
regulators with fixed and adjustable voltage options
available in popular packages.
APPLICATIONS
= Pentium® Processor supplies
= PowerPC™ supplies
= Other 2.5V to 3.6V microprocessor supplies
= Low voltage logic supplies
= Battery-powered circuitry
= Post regulator for switching supply
