Thought for 7 sec
Got it — I’ll add the exact-MPN description and 4–5 tags to the metadata after confirming them from the TI datasheet, then continue the cross-check.

LM2936Z-3.3/NOPB Part Review
Date: 2026-07-07 Official TI product page: https://www.ti.com/product/LM2936/part-details/LM2936Z-3.3/NOPB
Completed the datasheet-backed part review and updated the exact-MPN description, tags, datasheet metadata, manufacturer/type metadata, and pin descriptions. Full findings are in LM2936Z-3.3/NOPB Part Review.
Open items:
- Footprint pinout matches, but the 0.762 mm drill is smaller than TI’s example 0.85/0.9 mm holes for formed leads; review assembly preference before release.
Suggested next steps:
- Adjust the TO-92 hole size if you want to match TI’s example land pattern.
- Add recommended input/output capacitors as an application reference block.
- Run a final component publishing/metadata check.
Fix footprint and review
Fix drill size

Footprint cross-check
- Current footprint asset is named
LM2936Z-3.3/NOPB.kicad_modwith value textZ03A_TEX. - Footprint has 3 through-hole pads: pad 1 rectangular, pads 2 and 3 oval.
- Pad positions in the footprint are 0 mm, 1.27 mm, and 2.54 mm along one axis, matching the TI LP0003A TO-92 drawing convention of 1.27 mm adjacent lead spacing and 2.54 mm total span from pin 1 to pin 3.
- Drill size in the footprint is 0.762 mm. TI example board layout shows 0.85 mm and 0.9 mm hole examples for formed lead options; this footprint is therefore smaller than TI's example formed-lead land pattern holes, though the TO-92 lead diameter range is 0.38 mm to 0.55 mm. This is not an electrical pinout error, but it is a manufacturability/assembly choice to review.
- Package model asset is LP0003A, matching the TI TO-92 package outline.
Mismatches / risks flagged
- No pinout mismatch found: symbol pins 1/2/3 match OUT/GND/IN from the datasheet.
- No pad-count mismatch found: footprint has the expected 3 through-hole pads.
- Footprint lead spacing appears correct for inline TO-92: 1.27 mm adjacent pitch, 2.54 mm pin-1-to-pin-3 span.
- Footprint drill size is smaller than TI's example board-layout holes for formed leads; review intended straight/formed lead option and assembly process before release.
- Original metadata had generic description and exact MPN formatting using underscore; this was corrected to LM2936Z-3.3/NOPB.
