AZ1117H-1.2TRE1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-3

AZ1117H-1.2TRE1 from Diodes Incorporated, in a SOT-223-3. 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 / regulator common return. On fixed-output (1.2 V) variants this pin is the ground reference for the internal bandgap and reference divider; tie directly to the system 0 V plane.
2 VOUT power_out Regulated 1.2 V output (1.176-1.224 V typical, 1.152-1.248 V over full load/line). Rated for up to 1 A continuous. Requires a >=22 uF output capacitor for stability and ripple rejection; the SOT223 tab is internally connected to this pin.
3 VIN power_in Unregulated input supply. Recommended operating range up to 15 V, absolute maximum 20 V. Recommended input decoupling: 10 uF bulk capacitor close to the pin.

  • 3D model files: az1117h-1-2tre1-etched.step / az1117h-1-2tre1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); az1117h-1-2tre1.step / az1117h-1-2tre1.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
az1117h-1-2tre1.step 64 KB You want the bare part, or you mark your own boards.
az1117h-1-2tre1-etched.step 1.6 MB You want the part with AZ1117H-1.2TRE1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 448 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.

Provenance

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

  • Datasheet: Diodes Incorporated datasheet (32 pp, sha256 a54ad8d300c88315, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
