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.
