The LX8587/8587A series ICs are low
dropout three-terminal positive regulators
with a nominal 3A output current. Pen-
tium
Processor and Power PC
TM
appli-
cations requiring fast transient response
are ideally suited for this product family.
The LX8587A is
guaranteed to have
< 1.2V dropout at 3A
and the LX8587
< 1.3V at the same current,
making
them ideal to provide well-regulated out-
puts 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 3.1A to
ensure adequate output current and con-
trolled short-circuit current. On-chip
thermal limiting provides protection
against any combination of overload con-
ditions that would create excessive junc-
tion temperatures.
The LX8587/87A family of products are
available in both TO-220 through-hole
as well as TO-263 surface-mount pack-
ages. For higher current applications,
see the LX8585 and LX8584 data sheets.
