The LX8584/84A/84B series ICs are low drop-
out three-terminal positive regulators with a
nominal 7A output current. This product
family is ideally suited for Pentium
Proces-
sor and Power PC
TM
applications requiring
fast transient response. The LX8584A is
guar-
anteed to have < 1.2V at 7A
and the
LX8584/84B
< 1.4V at 7A dropout voltage,
making them ideal to provide well regulated
outputs of 2.5V to 3.6V using a 5V input
supply. In addition,
the LX8584B also of-
fers ±1% maximum voltage reference ac-
curacy over temperature
. Fixed versions
are also available and are specified in the
Available Options table below.
Current limit is trimmed above 7.1A to
ensure adequate output current and con-
trolled short-circuit current. On-chip ther-
mal limiting provides protection against any
combination of overload that would create
excessive junction temperatures.
The LX8584/84A series products are avail-
able in both the through-hole versions of
the industry standard 3-pin TO-220 and
TO-247 power packages.
The LX1431 Programmable Reference in
conjunction with the LX8584 7A LDO prod-
ucts offer precision output voltage (see ap-
plication below) and are ideal for use in VRE
applications.

Thick traces represent high current traces which must be low resistance /
low inductance in order to achieve good transient response.
