LP2997MX/NOPB Description

Short technical summary and product information.

The Texas Instruments LP2997MX/NOPB is a specialized linear regulator designed to meet JEDEC SSTL-18 specifications for DDR-II memory termination. It features a wide input voltage range from 1.8V to 5.5V and a precise output voltage range of 0.822V to 0.887V.

 

This regulator is capable of delivering 500mA continuous current with transient peaks up to 900mA, essential for DDR-II SDRAM termination. It includes a V_SENSE pin for superior load regulation and a V_REF output for chipset and DIMM referencing. The device also incorporates an active-low shutdown pin (SD) for Suspend To RAM (STR) functionality, allowing the V_TT output to tri-state while V_REF remains active, offering power savings through reduced quiescent current.

 

The LP2997MX/NOPB operates within a temperature range of 0°C to 125°C and has a typical quiescent current of 0.32mA. It is available in an 8-SOIC package, suitable for surface mount applications.

 

Key features include its linear topology, low output voltage offset, and low external component count, making it a robust solution for DDR-II memory systems.
