tmi3341.lbr rebuild the library on adom-lbr 2.32.0. 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 -> 6 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

TMI3341

TMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-6

TMI3341 from TMI, in a SOT-23-6. 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 BS passive Bootstrap pin. A capacitor (typ. 0.1µF) connected between LX and BS forms a floating supply for the high-side MOSFET gate driver.
2 GND power_in Ground pin. Device ground return for all internal circuitry and the low-side MOSFET.
3 FB input Output voltage feedback input. Connect to the center tap of the external resistor divider from VOUT. Internal reference VFB = 0.8V ±2%.
4 EN input Enable input. Drive logic-high to enable the IC, logic-low to disable and enter micro-power shutdown. EN rising threshold ~1.1V; do not leave floating. Max VEN = VIN.
5 IN power_in Power supply input, 4.5V to 30V (abs max 32V). Bypass with a low-ESR ceramic capacitor (e.g. 22µF + 100nF) close to the pin.
6 LX power_out Switching node. Common drain of the internal high-side and low-side power MOSFETs; connects to the external inductor and the bootstrap capacitor. Rated 1.2A continuous output current.

CAD (KiCad official)

  • Symbol: TMI3341
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: tmi3341-etched.step / tmi3341-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmi3341.step / tmi3341.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tmi3341.step 97 KB You want the bare part, or you mark your own boards.
tmi3341-etched.step 1.4 MB You want the part with TMI3341 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 355 faces against 117 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: TMI datasheet (12 pp, sha256 f6bbdb378fc7ebf0, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
