L I N D O C # 8582 LX8582A-xx 8 5 A LO W DR O P O U T PO S I T I V E RE G U L AT O R S PR O D U C T I O N DATASHEET The LX8582A series ICs are low dropout three-terminal positive regulators with 8.5A rated output current. Processor applications such as the 6x86TM & 6x86LTM, Processor and Power PCTM applications requiring fast transient response are ideally suited for this product family. The LX8582A series products are guaranteed to have < 1.3V at 8.5A and are ideal to provide well-regulated outputs of 2.5V to 3.6V using a 5V input supply in the adjustable version, or an output of 3.3V using a 5V input supply in the fixed version. Current limit is trimmed above 8.6A to ensure adequate output current and controlled short-circuit current. Onchip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures. The LX8582A series ICs are available in both the through-hole versions of the industry standard 3-pin TO-220 and TO247 power packages. For use in VRE applications, the LX1431 Programmable Reference in conjunction with this family of regulators offers precision output voltage. See the LX1431 data sheet for information on this product.
