Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix TLX indicates tape and reel packaging configuration. Confirm the NOPB designation ensures lead-free and RoHS compliance status. Cross-reference the manufacturer datasheet for the exact pinout and recommended external component values to ensure compatibility with your circuit design requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.5 V output is required without external feedback resistors. The DSBGA-5 package offers a small footprint suitable for dense PCB layouts. Ensure the application input voltage remains within the 2.7 V to 5.5 V operational range for proper regulation and stability.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3671 family of synchronous step-down converters. Variants like LM3671MFX-2.5/NOPB share similar electrical characteristics but differ in package type, using SOT-23-5 instead of DSBGA-5. The family is designed for portable applications requiring efficient power management from single-cell lithium-ion batteries.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM3671TL-2.5/NOPB is a direct equivalent with identical electrical specifications and package. LM3671MFX-2.5/NOPB serves as a functional substitute if SOT-23-5 packaging is acceptable for the design.
