The Texas Instruments LP2998MR is a linear regulator specifically designed to meet JEDEC SSTL-2 and JEDEC SSTL-18 specifications for DDR-SDRAM and DDR2 memory termination. It also supports DDR3 and DDR3L VTT bus termination with a minimum VDDQ of 1.35 V.
This regulator can deliver 1.5 A of continuous current and transient peaks up to 3 A, making it suitable for demanding DDR-SDRAM termination applications. Key electrical features include a shutdown pin for Suspend To RAM (STR) functionality, a VSENSE pin for superior load regulation, and a VREF output for chipset and DIMM reference.
The LP2998MR operates from an input voltage range of 1.35 V to 5.5 V, with an output voltage ranging from 0.656 V to 0.698 V. It has a typical quiescent current of 0.32 mA and an operating temperature range of -40°C to 125°C. The device is AEC-Q100 qualified with an HBM ESD Classification Level of H1C.
Packaged in an 8-pin SOIC (D) or HSOIC (DDA) with a surface mount type, the LP2998MR offers a compact solution for memory termination needs. Its output stage is designed to prevent shoot-through while ensuring reliable performance.
