        CXTP65156是一款为DDR内存总线的终端提供电源而专门设计的高性能线性稳压器，同以往开关型解决方案相比，它大大减少了外围器件的个数和占用的PCB空间，并降低了系统的整体成本。CXTP65156的高速运算放大器对负载具有快速优良的瞬态响应，CXTP65156还采用了VSENSE pin以达到优越的负载调整率；CXTP65156采用VREF输出为chipset和DIMMs提供基准电压。CXTP65156的另外一个特点是设计了低电压有效关断pin SD，当SD被拉低时，VTT的输出将处于高阻状态；但VREF依然保持在有效状态，在这种状态下，芯片因为其低的静态电流而功耗减小。CXTP65156利用与串联终端电阻连接的方式为高速传输线的有源终端结构提供优良的电压源。The CXTP65156 is a high performance linear regulator designed to provide power for termination of a DDR memory bus. It significantly reduces parts count, board space and overall system cost over previous switching solutions. The CXTP65156 contains a high-speed operational amplifier to provide excellent response to load transients. The CXTP65156 also incorporates a VSENSE pin to provide superior load regulation and a VREF output as a reference for chipset and DIMMs. An additional feature found on the CXTP65156 is an active low shutdown (SD ) pin. When SD is pulled low the VTT output will Tri-state providing a high impedance output, but, VREF will remain active. A power savings advantage can be obtained in this mode through lower quiescent current. The CXTP65156, 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.
