This datasheet includes multiple variants, all published together in a single manufacturer document.

General 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.

Key Features

  • expected of a voltage regulator: short circuit protection, safe operating area protection and automatic thermal shutdown if the device temperature rises above approximately 165°C. Use of an output capacitor is.
