The device can both source and sink up to 1.5A/3A of current while regulating an output voltage to within 2% (DDR-I) and 3% (DDR-II) or less. The UTC UR5515 is capable of use in conjunction with series termination resistors to provide 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.
