Part Number: LM2903
We purchased the LM2903QPWRQ1 material from two sources (batches 2202/2603) and conducted authenticity testing. After testing, we found that the lead frames of the two materials were inconsistent, but after opening the package, the trademark, model, version number, and layout of the Die surface inside were consistent. Please help determine whether they are the same material, and if so, whether TI has issued a PCN for the corresponding lead frame change.
