Description
The SE9174 regulator is designed to convert
voltage supplies ranging from 1.6V to 6V into a
desired output voltage, which is
adjusted by two
external voltage divider resistors. The regulator is
capable of sourcing or sinking up to 2.0A of current
while regulating an output voltage to within 2%
(DDR 1 or DDR 2) or less.
The SE9174, 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 back-plane
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.
