GENERAL DESCRIPTION
The SP2996B voltage regulator is designed to
convert voltage supplies ranging from 1.6V to
6V into a desired output voltage which is
adjusted by an external resistor divider.
The regulator is capable of sourcing or sinking
up to 2A of Continuous current while
regulating an output voltage to within 20mV.
The SP2996B provides an excellent voltage
source for active termination schemes of high
speed transmission lines such as those seen in
high speed memory buses and distributed
backplane designs when used in conjunction
with series termination resistors. The voltage
output of the regulator can be used as a
termination voltage for DDR SDRAM, and it
meets the JEDEC SSTL-2 and SSTL-3
specifications. Current limits in both sourcing
and sinking mode, plus on-chip thermal
shutdown make the circuit tolerant of output
fault conditions.
