1.5A/3A Bus Termination Regulator
General Description
The RT9173/A regulator is designed to convert
voltage supplies ranging from 1.8V to 6V into a
desired output voltage which adjusted by two external
resistors, voltage divider. The regulator is capable of
sourcing or sinking up to 1.5A/3A of current while
regulating an output voltage to within 2% or less.
The RT9173/A, 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.
Current limits in both sourcing and sinking mode, plus
on-chip thermal shutdown make the circuit tolerant of
the output fault conditions.
