UR5515

Note:1.Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2.The device is guaranteed to meet performance specification within 0~70 operating temperature range
and assured by design from 20~85.

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 UR5515 can be used as a termination voltage for DDR SDRAM.
