Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm that the non-Pb (lead-free) suffix variant, such as LM25007MM/NOPB, meets your environmental compliance requirements. Ensure the 8-VSSOP package dimensions align with your PCB footprint specifications. Cross-reference the manufacturer's latest documentation for any design-in restrictions or recommended alternatives.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a high-voltage input buck converter is required with minimal external parts. The fixed frequency operation simplifies EMI filtering compared to variable frequency controllers. Consider the 500mA current limit and 42V input rating against your load requirements. Evaluate the thermal performance in the VSSOP package for your specific ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM25007 family of simple switchers designed for cost-sensitive applications. It shares architectural similarities with other TI buck regulators but is distinguished by its specific input voltage range and non-synchronous topology. The MMX suffix indicates a tape-and-reel packaging format intended for automated assembly processes.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM25007MM/NOPB is documented as a direct substitute. Verify pin compatibility and ensure the RoHS-compliant version meets your regulatory needs. Other family members may require schematic adjustments due to different control architectures.
