LP2997MRX Description

Short technical summary and product information.

The LP2997MRX is a DDR-II termination regulator from Texas Instruments designed for memory termination applications. It operates from an input voltage range of 2.2V to 5.5V and provides a regulated output voltage of 0.822V to 0.887V. The device features a low quiescent current of 0.32mA, making it suitable for power-sensitive designs. It can source or sink 500mA continuous current with transient peaks up to 900mA, providing robust performance for DDR-II memory termination. The regulator is housed in an 8-SO PowerPad surface mount package, which offers enhanced thermal dissipation. The operating temperature range is -40°C to 125°C, allowing use in a wide variety of environments. The LP2997MRX is ideal for DDR-II memory modules, computing systems, and other applications requiring precise voltage regulation.
