DESCRIPTION
The LX8554 series ICs are very low dropout three-terminal positive regulators with 5A rated output current. This product family is ideally suited for Pentium® Processor and Power PCTM applications requiring fast transient response. The LX8554 is guaranteed to have a dropout voltage under 1V at 5A load, making it ideal to provide well-regulated outputs of 2.5V to 3.6V with input supply as low as 4.75V. Fixed versions are also available and are specified in the Available Options table below.
