AME9172

Bus Termination Regulator

nGeneral Description

The AME9172 is a voltage regulator which could con-

vert the input voltage ranging from 1.3V to 6V to an output

voltage that user settled. The regulator can provide sourc-

ing or sinking current. The AME9172 used in conjunc-

tion with series termination resistors, provides an excel-

lent 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.

Current limits in both sourcing and sinking mode, plus

on-chip thermal shutdown make the circuit tolerant of the

output fault conditions.
