DESCRIPTION
The LT ®1581 is a 10A 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 430mV at 10A. 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.

FEATURES
■ Low Dropout, 430mV at 10A Output Current
■ Fast Transient Response
■ Remote Sense
■ 1mV Load Regulation
■ Fixed 2.5V Output and Adjustable Output
■ No Supply Sequencing Problems in
   Dual Supply Mode

APPLICATIONS
■ 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
■ PowerPCTM Series Power Supplies
