RT9173B
2A Bus Termination Regulator
General Description
The RT9173B regulator 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 regulator is capable of sourcing or sinking up to 2A of current while regulating an output
voltage to within 40mV.
The RT9173B, 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
voltage output of the regulator can be used as a termination
voltage for DDR SDRAM.
