Description

The LP2994 regulator is designed to provide a linear solutionto 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 amplifierto provide linear regulation of VTT without the need forexpensive externalcomponents. The output stage preventsshoot through while delivering 1.5A continuous current andmaintaining excellent load regulation. The LP2994 also in-corporates an active low shutdown pin to tri-state the outputduring Suspend To Ram (STR) states.
