LT LT1580CQ

Overview

The LT1580CQ is a 7A low dropout regulator designed to power the new generation of microprocessors. The dropout voltage of this device is 100mV at light loads rising to just 540mV at 7A. To achieve this dropout, a second low current input voltage 1V greater than the output voltage, is required. The device can also be used as a single supply device where dropout is comparable to an LT1584.

This device is ideal for generating processor supplies of 2V to 3V on motherboards where both 5V and 3.3V supplies are available.
