The Texas Instruments LP2997MRX/NOPB is a specialized power management IC designed as a DDR-II termination regulator. It meets JEDEC SSTL-18 specifications for DDR-II memory termination.
Key electrical characteristics include an input voltage range from 1.8V to 5.5V and a precise output voltage range of 0.822V to 0.887V. The device features a low quiescent current of 320µA typical, contributing to power savings. It can deliver 500mA continuous current and transient peaks up to 900mA, essential for DDR-II SDRAM termination.
The regulator incorporates a V SENSE pin for superior load regulation and a V REF output for chipset and DIMM referencing. It also includes an active low shutdown (SD) pin for Suspend To RAM (STR) functionality, allowing the V TT output to tri-state while V REF remains active, further enhancing power efficiency.
Packaged in an 8-SO PowerPad surface-mount configuration, the LP2997MRX/NOPB is suitable for various board designs. Its operating temperature range is from 0°C to 125°C.
