The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 4 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

SPX1117M3-L-5-0

MaxLinear · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-3

SPX1117M3-L-5-0 from MaxLinear, in a SOT-223-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference for the regulator. On fixed-output variants (including the -5-0 5.0V option) this pin is the device ground; on adjustable variants the same pin functions as the ADJ feedback input (I_ADJ ≈ 50µA typ). For the SPX1117M3-L-5-0 tie directly to the system ground plane.
2 VOUT power_out Regulated 5.0V output (4.950V-5.050V typ at IOUT=5mA, VIN=6.5V). Requires a minimum 2.2µF ceramic (or 10µF tantalum/aluminum) output capacitor with ESR ≤0.5Ω for stability. Supplies up to 800mA guaranteed (1A peak), current-limited to 1.0-2.0A.
3 VIN power_in Unregulated input supply. For the 5.0V fixed option requires 6.4V ≤ VIN ≤ 12V over full load (absolute max 20V). Bypass with CIN=10µF recommended.
4 TAB power_out Heatsink tab, internally connected to VOUT. Solder to a copper pour tied to the VOUT net to conduct heat away from the die (θJA ≈ 46°C/W with adequate copper on FR-4). Do NOT connect to ground or any other net.

The extractor listed these alongside SPX1117M3-L-5-0, but they are different parts with different electrical characteristics. Do not order them as substitutes.

Two STEP files. Same geometry, different body top:

File Size Use it when
spx1117m3-l-5-0.step 64 KB You want the bare part, or you mark your own boards.
spx1117m3-l-5-0-etched.step 2.0 MB You want the part with SPX1117M3-L-5-0 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 521 faces against 75 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
