LP2998MR/NOPB Description

Short technical summary and product information.

The Texas Instruments LP2998MR/NOPB is a specialized linear regulator designed for DDR-SDRAM and DDR2 memory termination, also supporting DDR3 and DDR3L VTT bus termination. It delivers a continuous current of 1.5 A and transient peaks up to 3 A, meeting the demands of DDR memory termination.

 

Key electrical specifications include an input voltage range from 1.35 V to 5.5 V and a precise output voltage range of 0.656 V to 0.698 V. The device features a shutdown pin for Suspend To RAM (STR) functionality, allowing the VTT output to tri-state when the shutdown pin is pulled low. It also incorporates a VSENSE pin for superior load regulation and a VREF output for chipset and DIMM reference.

 

This regulator operates within a junction temperature range of -40°C to 125°C and has a low quiescent current of 0.32 mA typical. It is available in an 8-SO PowerPad package, suitable for surface mount applications. The device meets JEDEC SSTL-2 and JEDEC SSTL-18 specifications.
