Texas Instruments LP2997MX/NOPB
- Part Number:
- LP2997MX/NOPB
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3265799-LP2997MX/NOPB
- Description:
- DDR-II Termination Regulator
- Datasheet:
- lp2997
Description
The LP2997 linear regulator is designed to meet the JEDEC SSTL-18 specifications for termination of DDR-II memory. It contains a high-speed operational amplifier for excellent response to load transients. The output stage prevents shoot-through while delivering 500mA continuous current and transient peaks up to 900mA in the application as required for DDR-II SDRAM termination. The LP2997 also incorporates a VSENSE pin to provide superior load regulation and a VREF output as a reference for the chipset and DIMMs.
An additional feature found on the LP2997 is an active low shutdown (SD) pin that provides Suspend To RAM (STR) functionality. When SD is pulled low, the V output will tri-state providing a high impedance output, but, VREF will remain active. A power savings advantage can be obtained in this mode through lower quiescent current.
