Key Features

The LP2996MRX/NOPB is a linear regulator specifically designed to meet JEDEC SSTL-2 and SSTL-3 specifications for DDR-SDRAM termination. It can source and sink up to 1.5A continuously, ensuring reliable performance in high-speed memory applications. The output voltage precisely tracks half of the VDDQ supply, eliminating the need for external resistor dividers. With an input voltage range accommodating various system rails, it offers design flexibility. The device’s low quiescent current contributes to overall system power efficiency. Additionally, the Suspend to RAM (STR) functionality allows the regulator to tri-state the VTT output during low-power states, reducing power consumption. Thermal shutdown protection ensures safe operation under fault conditions. The compact 8-Pin SO PowerPAD package enhances heat dissipation, making it suitable for space-constrained designs.​TI

DDR1, DDR2, DDR3, and DDR3L Memory Termination
FPGA and ASIC Core Voltage Regulation
SSTL-2 and SSTL-3 Termination
HSTL Termination
Notebook and Desktop Computers
Servers and Workstations
Industrial and Medical PCs​

Product Overview

The LP2996MRX/NOPB serves as a robust solution for DDR memory termination, ensuring signal integrity and compliance with JEDEC standards. Its ability to both source and sink current maintains the required VTT voltage during dynamic memory operations. The regulator’s design eliminates the need for external components to set the output voltage, simplifying circuit design and reducing component count. Its wide input voltage range allows compatibility with various power rails commonly found in memory systems. The low quiescent current and STR functionality contribute to energy-efficient system designs, particularly important in portable and always-on applications. Thermal shutdown provides an additional layer of protection, safeguarding the device and surrounding components from excessive heat. The 8-Pin SO PowerPAD package not only saves board space but also enhances thermal performance, making it ideal for applications where efficient heat dissipation is crucial.​
