REL-SA9173 -AH-A Reliability Report for AT9173 Series Product Approved by Prepared by Amy Shen Quality & Reliability Dept. Manager Eric Chen Quality & Reliability Dept. Engineer Conclusion: The AT9173 series product has successfully met AME’s reliability standard that is required on all AME, Inc products. Furthermore, QRA Dept. of AME, Inc monitors the reliability continuously to make sure that all AT9173 series product will still meet AME’s reliability standard in the future. Table of Contents: Ⅰ、General Description Ⅱ、Product Information Ⅲ、Product Reliability Test Result Ⅳ、Package Reliability Test Result Ⅴ、IR-reflow Test Result Ⅰ、General Description: The AT9173 is a voltage regulator which could convert the input voltage ranging from 1.8V to 5V to an output voltage that user settled. The regulator can provide sourcing or sinking current. The AT9173, used in conjunction with series termination resistors, provides 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. Current limits in both sourcing and sinking mode, plus on-chip thermal shutdown make the circuit tolerant of the output fault conditions.
