General Description
LX8584B-xx General Description
The LX8584/84A/84B series ICs are low dropout three-terminal positive regulators with a nominal 7A output current. This product family is ideally suited for Pentium® Processor and Power PCTM applications requiring fast transient response. The LX8584A is guaranteed to have < 1.2V at 7A and the LX8584/84B < 1.4V at 7A dropout voltage,making them ideal to provide well regulated outputs of 2.5V to 3.6V using a 5V input supply. In addition, the LX8584B also offers ±1% maximum voltage reference accuracy over temperature. Fixed versions are also available and are specified in the Available Options table below.
Current limit is trimmed above 7.1A 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 LX8584/84A series products are available in both the through-hole versions of the industry standard 3-pin TO-220 and TO-247 power packages.
The LX1431 Programmable Reference in conjunction with the LX8584 7A LDO products offer precision output voltage (see application below) and are ideal for use in VRE applications.
