Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
I’ll audit the part metadata, source the official datasheet if needed, update the Datasheet property, then verify symbol pins and footprint against the manufacturer documentation.
Audit complete. The Datasheet URL was already populated, so it was not changed; the main mismatches are adjustable-variant title/description, non-orderable MPN shorthand, missing VOUT pin 2 representation, absent pin descriptions/types, and 1.7 mm small pads versus TI’s 2.15 mm example land pattern.
Full findings and key LM1117-1.8 specifications are in LM1117 Part Audit.
The footprint is substantially consistent with TI's NDP0003B (TO-252) package, but the part project is not internally identity-consistent. No part properties or geometry were changed because a Datasheet URL was already populated.

TI package is 3-pin; symbol terminals are numbered 1, 3, 4
TI lists the fixed-1.8 V NDP orderables as LM1117DT-1.8/NOPB (tube) and LM1117DTX-1.8/NOPB (tape-and-reel), plus .B variants. The exact carrier/orderable identity cannot be determined from the current shorthand MPN.
Key specifications for fixed 1.8 V LM1117
800 mA low-dropout linear regulator
Nominal output: 1.8 V
Output at 25 C, 10 mA, VIN = 3.8 V: 1.782 V to 1.818 V
Output across 0 C to 125 C: 1.746 V to 1.854 V
Recommended maximum VIN: 15 V
Absolute maximum VIN: 20 V
Dropout at 800 mA: 1.2 V typical at 25 C; 1.3 V maximum across temperature
Current limit at 25 C: 800 mA to 1500 mA; 1200 mA typical
Function correct; canonical name, description/type missing
OUT
4
Unspecified
Pin 2 and tab are VOUT
Output tab mapping is valid, but electrical pin 2 is omitted
The TI NDP electrical pinout is pin 1 = GND, pin 2 = VOUT, pin 3 = VIN, with the tab also connected to VOUT. The footprint's large land is numbered 4 in TI's NDP land-pattern drawing, so mapping symbol terminal 4 to the output tab is mechanically consistent. However, the symbol does not expose or document pin 2, leaving the pin-2/tab equivalence ambiguous.
Additional symbol issues:
All terminal electrical types are Unspecified.
Pin descriptions are absent.
Custom symbol text renders as missing-glyph boxes.
Footprint audit
The footprint asset is named LM1117DT-ADJ/NOPB.kicad_mod, which conflicts with the intended fixed-output identity, but the geometry targets NDP0003B.

Other mechanical findings:
TI nominal body: 6.58 x 6.10 mm
Package: NDP0003B / TO-252, 2.55 mm maximum height
A compatible NDP0003B.stp model is present
Fabrication geometry contains duplicated line groups near one lead; copper is unaffected
Source KiCad dimensions are in millimeters and appear correctly scaled
Layout inspection reports values such as 0.0013 while labeling the unit as mm; these appear to be internal meter values with a misleading displayed unit. If interpreted literally as mm the footprint would be 1000x too small, so this is a readout/unit-label ambiguity worth verifying visually or with an export
Flagged mismatches
Project title identifies the adjustable version.
Description identifies the adjustable version.
MPN is not an exact TI orderable number.
Package and pin-count properties are absent.
Symbol omits electrical pin 2 and does not document its equivalence to output tab/pad 4.
Pin descriptions and electrical types are absent.
Small pads are 1.7 mm long versus TI's 2.15 mm example land pattern.
Symbol text renders incorrectly.
Computed footprint readout has a meter/mm labeling ambiguity.
Recommended corrections
Select the exact orderable MPN: LM1117DT-1.8/NOPB or LM1117DTX-1.8/NOPB.
Rename the project/assets and rewrite the description for the fixed 1.8 V variant.
Set package metadata to NDP0003B / TO-252 and pin count to 3 where supported.
Add pin descriptions and appropriate electrical types.
Explicitly represent or document VOUT pin 2 and tab/pad 4 as the same electrical node.
Confirm whether the intended small-land length is TI's 2.15 mm example value; update if no alternate qualified land pattern is intended.
Repair the symbol font/glyph rendering.
Verify effective footprint scale in a dimensional export or board view.
