The UTC
UR5515
is a linear bus termination regulator and
designed to convert voltage supplies ranging from 1.6V~6.0V into a
desired output voltage, which adjusted by two external voltage
divider resistors. 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.
The voltage output of the regulator can be used as a termination
voltage for DDR SDRAM.
