General Description<\/h3>\n\n\n\n

The EC9175 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 capable of actively
sinking or sourcing up to 2A 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 programmed by externally forcing the REFEN pin voltage.
The EC9175 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. The EC9175 are available in the ESOP8 (Exposed Pad) surface mount
packages.<\/p>\n\n\n\n
