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
