DESCRIPTION
The EZ1584 series of high performance positive
voltage regulators are designed for use in applications
requiring low dropout performance at full rated current.
Additionally, the EZ1584 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 EZ1584 series are three terminal
regulators with fixed and adjustable voltage options
available in the popular TO-220 package.
FEATURES
Low dropout performance,
1.3V max. for EZ1584
Full current rating over line and temperature
Fast transient response
±2% total output regulation over line, load
and temperature
Adjust pin current max 90µA over temperature
Fixed/adjustable output voltage
Line regulation typically 0.015%
Load regulation typically 0.05%
TO-220 package
APPLICATIONS
Pentium® Processor supplies
