The LP2998MA/NOPB from Texas Instruments is a linear DDR termination regulator specifically designed to meet JEDEC SSTL-2 and JEDEC SSTL-18 specifications. It supports VTT bus termination for DDR, DDR2, DDR3, and DDR3L memory, requiring a minimum VDDQ of 1.35V. This regulator can deliver 1.5A of continuous current and handle transient peaks up to 3A, crucial for DDR-SDRAM termination.
Key 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 device operates over a wide temperature range of -40°C to 125°C (TJ) and is housed in an 8-SOIC package.
With its low output voltage offset, no external resistors required, and low external component count, the LP2998MA/NOPB simplifies design and reduces board space. Its high-speed operational amplifier ensures excellent response to load transients, making it suitable for demanding memory applications.
