illustrate

The LP2996 linear regulator is designed to meet the JEDEC SSTL-2 specification for termination DDR-SDRAM. The device contains a high-speed op-amp to provide superior load transient response. The output stage prevents the termination shooting of DDR-SDRAM by providing a continuous current of 1.5A and a transient peak of up to 3A for applications in the application. The LP2996 also features a V SENSE pin that provides superior load regulation and a V REF output as a chipset and DIMM reference.

An additional feature of the LP2996 is found to be an aggressive low shutdown (^SD) pin that provides suspend to memory (STR) functionality. When ^ SD is pulled down the V TT output tristate provides a high impedance output, however, V REF will remain active. Power saving advantage in this mode through lower quiescent current.
