一,产品概述(General Description)      

   The CXDR7577AMP is a simple, cost-effective and high-speed linear regulator designed to generate
termination voltage in double data rate (DDR) memory system to comply with the JEDEC SSTL_2 and
SSTL_18 or other specific interfaces such as HSTL,SCSI-2 and SCSI-3 etc. devices requirements. The
regulator is cJTMAable of actively sinking or sourcing up to 2.5A while regulating an output voltage to
within 40mV.The output termination voltage cab be tightly regulated to track 1/2VDDQ by two external
voltage divider resistors or the desired output voltage can be pro-grammed by externally forcing the
REFEN pin voltage.
    The CXDR7577AMP also incorporates a high-speed differential amplifier to provide ultra-fast response in
line/load transient. Other features include extremely low initial offset voltage, excellent load regulation, current
limiting in bi-directions and on-chip thermal shut-down protection.Built-in  softstart  function  avoids  a
misoperation by inrush current.
  The CXDR7577AMP are available in the ESOP-8surface mount packages.
