qx2303l50t.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 -> 3 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

QX2303L50T

QX Micro Devices · DC-DC Converters · SOT-23

QX2303L50T from QX Micro Devices, in a SOT-23. 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 Device ground / power return.
2 LX output Switching node - drain of the internal power NMOS. Connect to the boost inductor and Schottky diode anode. Absolute maximum LX voltage 7 V, peak switch current up to 1000 mA (typical current limit 800 mA).
3 VOUT power_in Output-voltage sense / device supply pin. Connect to the regulated output rail (nominally 5.0 V for the '50' suffix) after the Schottky diode; the internal feedback divider senses this node. Absolute maximum 7 V.

Ordering variants

Same part, different packaging or reel option.

CAD (KiCad official)

  • Symbol: QX2303L50T
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: qx2303l50t-etched.step / qx2303l50t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); qx2303l50t.step / qx2303l50t.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
qx2303l50t.step 59 KB You want the bare part, or you mark your own boards.
qx2303l50t-etched.step 2.0 MB You want the part with QX2303L50T already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 481 faces against 69 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: QX Micro Devices datasheet (14 pp, sha256 80cb4ae49c2e83f6, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
