The output capacitors must be low ESR and low ESL type for good transient response
regulators designed to provide 3A output
current.
PC™ applications requiring fast transient
response are ideally suited for this product
family.
<1.2 dropout at 3A and the LX8587 < 1.3V
at the same current, making them ideal to
provide well-regulated outputs of 2.5V to
3.6V using a 5V input supply.
versions are also available and specified in
the Available Options table below.

Current limit is trimmed about 3.1A to
ensure adequate output current and
controlled short-circuit current. On-chip
thermal limiting provides protection against
any combination of overload conditions that
would create excessive junction
temperatures.
The LX8587/87A family of products are
available in the TO-220 through hole, the
TO-263 surface-mount, and the TO-252
surface-mount packages. For higher current
applications see the LX8585 and the
LX8584 data sheets.
