The
performance, very low dropout voltage
regulator, designed for use with
advanced
microprocessors,
controllers,
or
controllers. This product can be used
with separate voltage supplies for the
control and power sections, allowing a
power regulation dropout voltage as
low as 100mV @ 1.5A. In AGP bus
systems requiring regulation of 3.3V
to 2.85V @ 3A, the LX8580A has a
max dropout of 250mV making it an
ideal power supply solution for today’s
graphics applications.
The LX8580A can also be used in a
single voltage supply configuration
with
a

LX8580A
is
micro
graphics
video
performance
similar to that of the LX8584 (1.3V @
7.5A).
The LX8580A is supplied in a five-
terminal
TO-220,
Linfinity’s S-PAK packages, which
allows the implementation of remote
(Kelvin) voltage sensing. This sensing
compensates
for
variations due to load changes and
resistive voltage drops in connectors
and board traces. Typical load
regulation measured at the sense pin is
less that 1mV for a load current step of
7mA to 7.5A.
The LX8580A is ideal for generating a
secondary 2V-2.85V low voltage supply
on a motherboard where a 3.3V supply
is already available.
