QX2304L33T

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

QX2304L33T 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 return. Connect to system ground plane with a low-impedance path.
2 LX power_out Power switch drain / inductor switching node. Connect the boost inductor (typ. 47uH) between VIN and LX. Maximum switch current 1000mA (typ. ILIMIT 800mA).
3 VOUT power_out Regulated output voltage sense/feedback pin. Connect output capacitor (typ. 100uF) from VOUT to GND. Internally trimmed to 3.3V (L33 option), ±2.5% accuracy, max rating 7V.

CAD (KiCad official)

  • Symbol: QX2304L33T
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: qx2304l33t-etched.step / qx2304l33t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); qx2304l33t.step / qx2304l33t.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
qx2304l33t.step 59 KB You want the bare part, or you mark your own boards.
qx2304l33t-etched.step 2.0 MB You want the part with QX2304L33T already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 472 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 d147751aef814a16, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
