LP2996MR Description

The LP2996MR from Texas Instruments is a specialized DDR termination regulator designed to provide precise voltage regulation for DDR memory systems. Operating within a 2.2V to 5.5V supply range, it delivers stable termination voltage with a low 320µA supply current, making it highly efficient for power-sensitive applications. Housed in an 8-SOPWRPAD package, this surface-mount IC is RoHS3 compliant and rated for 0°C to 125°C, ensuring reliability across industrial environments. Although marked as obsolete, it remains a robust solution for legacy designs requiring DDR termination.

LP2996MR Features

• Wide Input Voltage Range (2.2V–5.5V): Supports flexible power supply configurations.
• Low Quiescent Current (320µA): Minimizes power dissipation in standby modes.
• DDR-Specific Termination: Optimized for DDR1, DDR2, and DDR3 memory interfaces.
• Industrial Temperature Range (0°C–125°C): Suitable for harsh operating conditions.
• RoHS3 Compliance: Meets environmental standards for lead-free designs.
• Moisture Sensitivity Level (MSL 3): Requires careful handling but offers 168 hours of floor life after exposure.

LP2996MR Applications

• Memory Modules: Ideal for DDR termination in servers, workstations, and embedded systems.
• High-Speed Data Buses: Ensures signal integrity in FPGA- and ASIC-based designs with DDR interfaces.
• Legacy System Upgrades: Provides a drop-in solution for older DDR-based hardware.
• Industrial Electronics: Suitable for automation controllers and telecom infrastructure due to its wide temperature tolerance.

Conclusion of LP2996MR

The LP2996MR is a high-performance DDR termination regulator offering low power consumption, broad voltage compatibility, and industrial-grade reliability. While obsolete, its optimized design for DDR memory systems makes it a viable choice for legacy applications or designs requiring proven performance. Engineers seeking a stable, efficient termination solution for DDR interfaces will find this IC well-suited to their needs.
