            Currents are positive into, negative out of the specified terminal.

The LX8585-xx/85A Series ICs are low dropout three-terminal regulators with a minimum of 4.6A output current. Pentium^® Processor and Power PC^TM applications requiring fast transient response are ideally suited for this product family. The LX8585A is guaranteed to have < 1.2V at 4.6A, while the LX8585 are specified for 1.4V, 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  Apecified in the Available Options table below.

Current limit is trimmed above 4.6A to ensure adequate output current and controlled short-circuit current. On-chip thermal limiting provides protection against any possible overload that would create excessive junction temperatures.The LX8585-xx/85A family is available in both through-hole and surface-mount versions of the industry standard 3-pin
TO-220 / TO-263 power packages.

The LX1431 Programmable Reference and LX8585-xx Series products offer precision output voltage and are ideal for use in VRE applications (see application below). For higher current applications, see the LX8584 data sheet.
