The LX8585/85A Series ICs are low drop-
out three-terminal regulators with a mini-
mum of 4.6A output current. Pentium
Processor and Power PC
TM
applications
requiring fast transient response are ide-
ally suited for this product family. The
LX8585A is
guaranteed to have < 1.2V
at 4.6A,
while the LX8585 are specified
for 1.4V, making them ideal to provide
well regulated outputs of 2.5V to 3.6V
using a 5V input supply. Fixed versions
are also available and specified in the
Available Options table below.
Current limit is trimmed above 4.6A to
ensure adequate output current and con-
trolled short-circuit current. On-chip
thermal limiting provides protection
against any possible overload that would
create excessive junction temperatures.
The LX8585/85A family is available in
both through-hole and surface-mount
versions of the industry standard 3-pin
TO-220 / TO-263 power packages.
The LX1431 Programmable Reference
and LX8585A Series products offer pre-
cision output voltage and are ideal for
use in VRE applications (see application
below). For higher current applications,
see the LX8584 data sheet.
