DESCRIPTION
The LX8580 is a high-performance, very low dropout voltage regulator, designed for use with advanced microprocessors. This product can be used with separate voltage supplies for the control and power sections, allowing a power section dropout voltage as low as 100mV. The LX8580 can also be used in a single voltage supply configuration, with a dropout performance similar to that of the LX8584 (1.3V at 7A).
KEY FEATURES
■ Low Dropout, 800mV Max. at 7A Output Current in Dual Supply Mode
■ Fast Transient Response
■ Remote Sensing
□ 1mV Load Regulation
□ Adjustable Output
□ No Supply Sequencing Problems in Dual Supply Mode
APPLICATIONS
■ Microprocessor Supplies
■ 3.3V to 2.5V Processor Power Supplies
■ High-Current Regulators
■ Post Regulators for Switching Supplies
