DESCRIPTIOON
The AP1280AMP 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 pro-grammed by
externally forcing the REFEN pin voltage.
The AP1280AMP 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 AP1280AMP are available in the ESOP-8
(Exposed Pad) surface mount packages.
