Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., MM vs MMX) against the required packaging format, as the base model may denote tape-and-reel or cut-tape variations depending on distributor classification. Confirm RoHS compliance status, as older revisions may differ from current NOPB designations. Cross-reference the datasheet revision date to ensure compatibility with latest application notes regarding boot capacitor regulation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for moderate current loads up to 500mA. The fixed on-time architecture simplifies external component selection compared to frequency-fixed converters. Ensure the input voltage does not exceed the 42V absolute maximum rating. Consider the VSSOP package size constraints for PCB layout if space is limited.

Voltage Regulators - DC DC Switching Regulators Part Context

The LM25007 belongs to the SIMPLE SWITCHER family of power management ICs. It serves as a cost-effective alternative to synchronous rectifiers in applications where efficiency requirements are moderate. The device complements higher-voltage variants like the LM5007, which support inputs up to 75V, while offering a more compact footprint for lower voltage domains.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM25007MM/NOPB is the direct lead-free replacement. LM25007SD/NOPB offers the same electrical performance in a WSON-EP-8 package.
