The AME9172 is a voltage regulator which could convertthe input voltage ranging from 1.5V to 6V to an outputvoltage that user settled. The regulator can provide sourcingor sinking current. The AME9172 used in conjunctionwith series termination resistors, provides an excellentvoltage source for active termination schemes of highspeed transmission lines as those seen in high speedmemory buses and distributed backplane designs.The voltage output of the regulator can be used as atermination voltage for DDR SDRAM.Current limits in both sourcing and sinking mode, pluson-chip thermal shutdown make the circuit tolerant of theoutput fault conditions.
