PRODUCTION DATA SHEET
DESCRIPTION
The LX8586/86A series ICs are Current limit is trimmed above 6.1A
low dropout three-terminal regulators to ensure adequate output current and
with a minimum of 6A output current. controlled short-circuit current. On-chip
Pentium^® Processor, Power PCTM, thermal limiting provides protection
Cyrix^® 6x86TM and AMD-K5™ against any combination of overload
applications requiring fast transient that would create excessive junction
response are ideally suited for this temperatures. The LX8586/86A series
product family. The LX8586A is devices are available in both through-
guaranteed to have < 1.1V at 6A and hole versions of the industry-standard,
the LX8586 < 1.3V at 6A dropout 3-pin TO-220 power packages. Along
voltage, making them ideal to provide with the standard μP supply
well-regulated outputs of 2.5V to 3.6V applications, the LX8586 series of
