Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required output voltage and package type. Confirm RoHS compliance status and lead times through authorized distributors. Cross-reference the part number with official Texas Instruments documentation to validate pinout assignments and electrical specifications before integration into design projects.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required from higher input voltages up to 40V. Consider the 1A current limit and 260kHz switching frequency for applications prioritizing efficiency over size. Evaluate the SOIC-8 package constraints regarding thermal dissipation and PCB layout requirements compared to adjustable variants or through-hole alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2675 family of simple switcher regulators, which are known for their ease of use and robust performance. The MX suffix indicates a surface-mount SOIC package variant, distinguishing it from the through-hole MDIP versions like the LM2675N series. The NOPB designation confirms lead-free manufacturing compliant with environmental standards.
