LP2994
DDR Termination Regulator
General Description
The LP2994 regulator is designed to provide a linear solution
to meet the JEDEC SSTL-2 and SSTL-3 specifications (Se-
ries Stub Termination Logic) for active termination of DDR-
SDRAM. The device utilizes an internal operational amplifier
to provide linear regulation of V
TT
without the need for
expensive external components. The output stage prevents
shoot through while delivering 1.5A continuous current and
maintaining excellent load regulation. The LP2994 also in-
corporates an active low shutdown pin to tri-state the output
during Suspend To Ram (STR) states.
