LP2997MR Description

Short technical summary and product information.

The Texas Instruments LP2997MR is a specialized linear regulator designed to meet JEDEC SSTL-18 specifications for DDR-II memory termination. It features a high-speed operational amplifier for excellent transient response and an output stage that prevents shoot-through, delivering 500mA continuous current and transient peaks up to 900mA.

 

Key electrical specifications include an input voltage range of 1.8V to 5.5V and a precisely regulated output voltage between 0.822V and 0.887V. The device operates with a low quiescent current of 0.32mA (typical) and is suitable for Suspend To RAM (STR) functionality via its active low shutdown pin.

 

Packaged in an 8-SO PowerPad (8-PowerSOIC) surface-mount configuration, the LP2997MR is designed for efficient integration into DDR-II memory systems. Its operating temperature range is from 0°C to 125°C, making it suitable for a variety of computing and embedded applications requiring reliable DDR memory termination.
