L I N D O C # 8586 LX8586-xx/8586A-xx 6A LOW DROPOUT POSITIVE REGULATORS PR O D U C T I O N DATASHEET The LX8586/86A series ICs are low dropout three-terminal regulators with a minimum of 6A output current. Processor, Power PCTM, 6x86TM and AMD-K5TM applications requiring fast transient response are ideally suited for this product family. The LX8586A is guaranteed to have < 1.1V at 6A and the LX8586 < 1.3V at 6A dropout voltage, 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 6.1A to ensure adequate output current and controlled short-circuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures. The LX8586/86A series devices are available in both through-hole versions of the industry-standard, 3-pin TO-220 and TO-247 power packages. Along with the standard µP supply applications, the LX8586 series of products are ideal for Pro Processor applications such as GTL+ Bus terminators see application below .
