DESCRIPTION
The EZ1585B is a high performance positive voltage
regulator designed for use in applications requiring low
dropout performance at full rated current. Additionally,
the EZ1585B 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 EZ1585B has tight tolerance on
reference voltage, ±1% at 25°C and ±1.5% over line,
load and temperature. The EZ1585B is a three
terminal regulator with adjustable output voltage
available in the popular TO-220 package.
FEATURES
= Low dropout performance, 1.3V max.
= Full current rating over line and temperature
= Fast transient response
= ±1.5% total output regulation over line, load and
temperature
= Adjust pin current max. 100µA over temperature
= Adjustable output voltage
= Line regulation typically 0.015%
= Load regulation typically 0.05%
= TO-220 package
APPLICATIONS
= Pentium® Processor supplies
