THE INFINITE POWER OF INNOVATION
7A VERY LOW DROPOUT POSITIVE ADJUSTABLE REGULATOR

PRODUCTION DATA SHEET

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 .

The LX8580 is supplied in a five terminal TO220 package, which allows the implementation
of remote Kelvin voltage sensing. This sensing compensates for output voltage variations due to load changes and resistive voltage drops in connectors and board traces. Typical load regulation measured at the sense pin is less than 1mV for a load current step of 7mA to 7A.

The LX8580 is ideal for generating a secondary 2 - 2.5V low voltage supply on a motherboard where a 3.3V supply is already available.
