Voltage Regulators - DC DC Switching Regulators datasheet and documents for LP2996MR
Voltage Regulators - DC DC Switching Regulators Overview
The LP2996MR is a specialized Power Management IC (PMIC) manufactured by Texas Instruments, originally developed under the National Semiconductor brand. It functions as a DDR termination regulator designed for high-speed memory applications. The device operates within an input voltage range of 1.8 V to 5.5 V and delivers an output current of 1.5 A. It supports a maximum output voltage of 900 mV with a quiescent input current of 320 uA. The component is housed in an 8-pin SO-PowerPad package and is rated for operation between 0°C and +125°C.
Voltage Regulators - DC DC Switching Regulators Feature Summary
- Integrated shutdown pin functionality for power management control
- Designed specifically for DDR2 termination requirements
- High output current capability of 1.5 A
Voltage Regulators - DC DC Switching Regulators Applications
- DDR2 memory termination circuits
- High-speed digital system power management
- Server and workstation memory subsystems
Voltage Regulators - DC DC Switching Regulators Procurement Notes
Verify the manufacturer designation carefully, as Texas Instruments acquired National Semiconductor. Confirm the specific suffix (e.g., NOPB) for RoHS compliance status. Check current availability as some variants may be discontinued or have limited stock. Ensure the package type matches the PCB footprint requirements.
Voltage Regulators - DC DC Switching Regulators Selection Notes
Select this component when a dedicated linear regulator for DDR termination is required. Consider the 1.5 A output current limit and 900 mV max output voltage against system specifications. Evaluate thermal performance given the SO-PowerPad package and operating temperature range up to 125°C. Verify compatibility with the target DDR standard.
Voltage Regulators - DC DC Switching Regulators Part Context
This part belongs to the LP2996 series of DDR termination regulators. It represents the legacy National Semiconductor design now managed by Texas Instruments. The MR suffix indicates the SO-PowerPad-8 package variant. It is distinct from other PMICs in the portfolio due to its specific focus on memory termination rather than general-purpose regulation.
Voltage Regulators - DC DC Switching Regulators Replacement Considerations
LP2996MR/NOPB is a verified lead-free and RoHS-compliant equivalent of the LP2996MR. Both share identical electrical characteristics and pinouts. Verify that the replacement meets all environmental and regulatory requirements for the final assembly.
