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 -> 5 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

TPSPX3819M5-L-5-0

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPSPX3819M5-L-5-0 from TECH PUBLIC, in a SOT-23-5. 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 VIN power_in Input supply voltage. Recommended operating range 2.0 V to 20 V (absolute max 24 V). Bypass to GND with a 1 µF ceramic capacitor close to the pin.
2 GND power_in Device ground reference and return for input and output currents.
3 EN input Enable control input. VIH ≥ 1.1 V turns the regulator on; VIL ≤ 0.4 V puts the device in shutdown (ISD ≈ 0.01 µA typ). Input current ~10 nA at VEN = 27 V. Do not leave floating; tie high to enable.
4 NC unconnected No internal connection. May be left floating or tied to GND for improved thermal/mechanical stability.
5 VOUT power_out Regulated 5.0 V output (±2% accuracy). Delivers up to 500 mA with current-limit and thermal-shutdown protection. Requires a 1 µF ceramic or tantalum output capacitor for stability.

  • 3D model files: tpspx3819m5-l-5-0-etched.step / tpspx3819m5-l-5-0-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpspx3819m5-l-5-0.step / tpspx3819m5-l-5-0.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tpspx3819m5-l-5-0.step 85 KB You want the bare part, or you mark your own boards.
tpspx3819m5-l-5-0-etched.step 2.7 MB You want the part with TPSPX3819M5-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: 672 faces against 102 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.
