Product Summary

The LT1580CT 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 of the LT1580CT can also be used as a single supply device where dropout is comparable to an LT1584. The applications of the LT1580CT include Microprocessor Supplies, Post Regulators for Switching Supplies, High Current Regulators, 5V to 3.XXV for Pentium Processors Operating at 90MHz to 166MHz and Beyond, 3.3V to 2.9V for Portable Pentium Processor, Power PCTM Series Power Supplies.
