6A LOW DROPOUT POSITIVE REGULATORS

DESCRIPTION
The LX8586/86A series ICs are low
dropout three-terminal regulators with
a minimum of 6A output current.
Pentium® Processor, Power PCTM,
Cyrix® 6x86TM and AMD-K5TM applica-
tions requiring fast transient response
are ideally suited for this product
family. The LX8586A is guaranteed to
have
< 1.1V at 6A and the LX8586 < 1.3V at
6A dropout voltage, 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 6.1A
to ensure adequate output current and
controlled short-circuit current.
On-chip thermal limiting provides
protection against any combination of
overload that would create excessive
junction temperatures.
The LX8586/86A series devices are
available in both through-hole versions
of the industry-standard, 3-pin TO-220
and TO-247 power packages.
Along with the standard µP supply
applications, the LX8586 series of
products are ideal for Pentium® Pro
Processor applications such as GTL+
Bus terminators (see application below).
