LP2994M/NOPB Description

The LP2994M/NOPB regulator is designed to provide a linear solution to meet the JEDEC SSTL-2 and SSTL-3 specifications (Series Stub Termination Logic) for active termination of DDR-SDRAM. The LP2994M/NOPB utilizes an internal operational amplifier to provide linear regulation of VTT 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 LP2994M/NOPB also incorporates an active low shutdown pin to tri-state the output during Suspend To Ram (STR) states.
