SE9174 General 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.
