LP2995 DDR Termination Regulator

Check for Samples: LP2995

FEATURES

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 amplifier 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.
