Product Summary

The RT9173BGS is a 2A Bus Termination Regulator. It is designed to convert voltage supplies ranging from 1.7V to 6V into a desired output voltage of which adjusted by two external voltage divider resistors. The RT9173BGS is capable of sourcing or sinking up to 2A of current while regulating an output voltage to within 40mV. The applications of the RT9173BGS include DDR Memory Termination Supply, Active Termination Buses, Desktop PC/AGP Graphics, Set Top Box/IPC, and Supply Splitter.
