Product Summary

The AT9173EG is a voltage regulator which could convert the input voltage ranging from 1.8V to 5V to an output voltage that user settled. The regulator can provide sourcing or sinking current. The AT9173EG, used in conjunction with series termination resistors, provides an excellent voltage source for active termination schemes of high speed transmission lines as those seen in high speed memory buses and distributed backplane designs. The applications of the AT9173EG include DDRI/DDRII Memory Termination Supply, Active Termination Buses, Desktop PC,NoTebook,Server and workstation, Graphic Card, Set Top Box, Embedded System.
