LP2995
DDR Termination Regulator
General Description
The LP2995 linear regulator is designed to meet the JEDEC
SSTL-2 and SSTL-3 specifications for termination of DDR-
SDRAM. The device contains a high-speed operational am-
plifier to provide excellent response to load transients. The
output stage prevents shoot through while delivering 1.5A
continuous current and transient peaks up to 3A in the
application as required for DDR-SDRAM termination. The
LP2995 also incorporates a V
SENSE
pin to provide superior
load regulation and a V
REF
output as a reference for the
chipset and DDR DIMMS.
