AP2111H-3.3TRG1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

AP2111H-3.3TRG1 from Diodes Incorporated, in a SOT-223. 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. Also serves as the thermal tab on SOT-223; should be connected to a copper pour for heat dissipation.
2 VOUT power_out Regulated 3.3V output, capable of sourcing 600mA continuous. Requires ≥1.0µF ceramic/tantalum/aluminum-electrolytic output capacitor for stability.
3 VIN power_in Input supply voltage, 2.5V to 6.0V recommended (6.5V absolute max). Bypass with a low-ESR capacitor close to the pin.

CAD (KiCad official)

  • Symbol: AP2111H-3.3TRG1
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223 (KiCad packages3D, STEP)
  • 3D model files: ap2111h-3-3trg1-etched.step / ap2111h-3-3trg1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ap2111h-3-3trg1.step / ap2111h-3-3trg1.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ap2111h-3-3trg1.step 64 KB You want the bare part, or you mark your own boards.
ap2111h-3-3trg1-etched.step 2.2 MB You want the part with AP2111H-3.3TRG1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 561 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.
