AZ1117H-3.3TRG1

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

AZ1117H-3.3TRG1 from Diodes, 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 fixed-output (3.3V) regulator. On adjustable versions this pin is the ADJ feedback pin, but on fixed-voltage variants (e.g. AZ1117H-3.3) this pin is connected internally as GND.
2 OUTPUT power_out Regulated 3.3V output (typ 3.3V, tolerance approx +/-1% at 10mA). Supplies up to 1A continuous. A minimum 22uF (tantalum recommended) output capacitor is required for stability.
3 INPUT power_in Unregulated input supply, absolute max 20V, recommended operating max 15V. Must exceed VOUT by the dropout voltage (typ 1.15V at 1A). A 10uF input capacitor is recommended.

CAD (KiCad official)

  • Symbol: AZ1117H-3.3TRG1
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223 (KiCad packages3D, STEP)
  • 3D model files: az1117h-3-3trg1-etched.step / az1117h-3-3trg1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); az1117h-3-3trg1.step / az1117h-3-3trg1.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
az1117h-3-3trg1.step 64 KB You want the bare part, or you mark your own boards.
az1117h-3-3trg1-etched.step 2.0 MB You want the part with AZ1117H-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: 520 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.
