Buying FAQ — LM2596S-5.0

Answer-first notes for stock, authenticity, lead time and quoting. Marked up as FAQPage.

Is LM2596S-5.0 the same as generic “LM2596 modules”?

The IC is a TI (or licensed) buck regulator; cheap modules may use unbranded clones. For OEM production, specify the exact MPN and package (S = TO-263) and avoid unlabeled bare dies.

LM2596S-5.0 vs LM2596S-ADJ?

5.0 is fixed 5 V output; ADJ is adjustable via feedback resistors. Do not swap without redesigning the feedback network.

What should I include in an RFQ for LM2596S-5.0?

Qty, packaging (tube/reel), temperature grade if any, and whether you accept alternate date codes. We return stock + reference unit price.

Common failure modes buyers should watch?

Overheating from poor PCB copper, wrong inductor and counterfeit markings. Ask for thermal layout notes and authentic TI packaging when possible.
