LP2998 Description

Short technical summary and product information.

The Texas Instruments LP2998 is a high-performance linear regulator specifically designed for DDR-SDRAM and DDR2 memory termination, meeting JEDEC SSTL-2 and SSTL-18 specifications. It also supports DDR3 and DDR3L VTT bus termination with a minimum VDDQ of 1.35V.

This regulator delivers 1.5A of continuous current and can handle transient peaks up to 3A, ensuring stable termination for DDR memory interfaces. Key electrical specifications include an input voltage range from 1.35V to 5.5V and a precise output voltage range of 0.656V to 0.698V. The device features a shutdown pin for Suspend To RAM (STR) functionality, allowing the VTT output to tri-state.

With a typical quiescent current of 0.32mA and an operating temperature range of -40°C to 125°C, the LP2998 is suitable for various applications. It is available in HSOIC (DDA) and SOIC (D) packages, both measuring 4.9 mm x 6 mm. The AEC-Q100 qualified device also includes a VSENSE pin for superior load regulation and a VREF output for chipset and DIMM reference.
