LP2998MAX/NOPB

Special Purpose Regulators Overview

The LP2998MAX/NOPB is a specialized power management integrated circuit designed as a 1.5A DDR termination regulator. It features an integrated shutdown pin for S3 state control and supports DDR, DDR2, DDR3, and DDR3L memory types. The device operates with an input voltage range of 1.35V to 5.5V and provides a minimum output voltage (VTT) of 0.677V. Typical quiescent current is 0.32mA. It functions within an operating temperature range of -40°C to +125°C and is housed in an SO PowerPAD-8 package.

Special Purpose Regulators Feature Summary

• Integrated shutdown pin enabling S3 state control for power management
• Supports multiple DDR memory standards including DDR, DDR2, DDR3, and DDR3L
• High current capability of 1.5A for effective termination regulation

Special Purpose Regulators Applications

• DDR memory termination circuits
• DDR2 memory termination circuits
• DDR3 memory termination circuits
• DDR3L memory termination circuits

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'MAX' corresponds to the SO PowerPAD-8 package variant when sourcing. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance status. Ensure the component meets automotive or industrial temperature requirements if operating near the upper limit of the specified range. Cross-reference datasheet revisions to confirm parameter consistency.

Special Purpose Regulators Selection Notes

Select this component when a dedicated linear regulator is required for high-current DDR termination applications. It is suitable for designs requiring precise VTT tracking and low quiescent current consumption. Consider the thermal performance of the SO PowerPAD-8 package for heat dissipation needs. Verify compatibility with the target memory generation's voltage specifications before integration.

Special Purpose Regulators Part Context

This part belongs to Texas Instruments' LP2998 family of DDR termination regulators. Variants such as LP2998MR/NOPB share similar electrical characteristics but differ in packaging. The MAX suffix specifically denotes the SO PowerPAD-8 form factor, distinguishing it from other package options within the same functional series.

Special Purpose Regulators Replacement Considerations

LP2998MR/NOPB serves as a functional alternative with identical electrical specifications but utilizes an HSOP-8 package instead of the SO PowerPAD-8. Verify footprint compatibility and thermal management requirements when substituting between these package variants.
