Product Overview
The LP2997MRX/NOPB is a linear regulator IC from Texas Instruments, specifically designed for DDR memory termination applications. It provides a low-noise, high-accuracy output voltage (VTT) that tracks VDDQ/2, ensuring proper termination for DDR, DDR2, DDR3, and DDR4 SDRAM. Housed in an 8-SO-POWERPAD package, it offers excellent thermal performance and a compact footprint. The device supports input voltages from 2.5V to 3.3V and delivers up to 1.5A of continuous output current, making it ideal for high-performance computing and communication systems.
