Part Information Review — LMR36503RFRPER

Completed the review and updated the part’s Datasheet URL to the official TI datasheet. I created the detailed findings in Part Information Review — LMR36503RFRPER.
Open items:
- The part exposes 13 terminals, but TI defines LMR36503RFRPER as a 9-pin RPE/VQFN-HR package.
- Pins 10–13 appear to be segmented footprint copper exposed as independent schematic pins.
- Pin types/descriptions are incomplete, and I filed an internal part-quality report.
Suggested next steps:
- Remap the symbol to the 9 datasheet pins.
- Tie segmented footprint copper to the correct real pins.
- Populate pin types/descriptions from TI Table 6-1.
