DESCRIPTION
The LX8580A is a highperformance, very low dropout voltage regulator, designed for use with advanced microprocessors, microcontrollers, or video graphics controllers. This product can be used with separate voltage supplies for the control and power sections, allowing a power regulation dropout voltage as low as 100mV @ 1.5A. In AGP bus systems requiring regulation of 3.3V to 2.85V @ 3A, the LX8580A has a max dropout of 250mV making it an ideal power supply solution for today’s graphics applications.
