1.5A/3A BUS TERMINATION

REGULATOR

ꢀ

DESCRIPTION

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.

TO-252-5

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.
