DESCRIPTION The LX8587/8587A series ICs are low dropout three-terminal positive
regulators with a nominal 3A output current. Pentium® Processor and Power PCTM applications 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 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 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 both TO-220 through-hole as well as TO-263 surface-mount packages. For higher current applications, see the LX8585 and LX8584 data sheets.
