Built-In Thermal Shutdown

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.
