AZ1117D-3.3TRE1

Diodes · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2

AZ1117D-3.3TRE1 from Diodes, in a TO-252-2. 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 3.3V regulator (this pin becomes ADJ on the -ADJ adjustable variant). Ties the internal reference and error-amplifier return to system ground; carries the quiescent current (~5 mA typ, 10 mA max).
2 OUTPUT power_out Regulated 3.3V output (VOUT = 3.3V nominal, 1A max continuous). Requires a 22µF (tantalum recommended) or larger output capacitor for stability and to meet the PSRR/dropout specs. Internally current-limited to ~1.35A typ; thermal shutdown activates at TJ ≈ +150°C.
3 INPUT power_in Unregulated DC input, VIN. Recommended operating range up to 15V (absolute maximum 20V). Must be at least VOUT + VDROP (≥ ~4.45V at 1A load for the 3.3V version). A 10µF input bypass capacitor to GND is recommended near the pin.
TAB OUTPUT (Tab) power_out Exposed metal heat-sink tab on the back of the TO-252 package, electrically common with pin 2 (OUTPUT). Solder to a copper pour tied to VOUT for thermal dissipation; θJC ≈ 17 °C/W for TO252-2.

CAD (KiCad official)

  • Symbol: AZ1117D-3.3TRE1
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252-2 (KiCad packages3D, STEP)
  • 3D model files: az1117d-3-3tre1-etched.step / az1117d-3-3tre1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); az1117d-3-3tre1.step / az1117d-3-3tre1.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
az1117d-3-3tre1.step 119 KB You want the bare part, or you mark your own boards.
az1117d-3-3tre1-etched.step 1.9 MB You want the part with AZ1117D-3.3TRE1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 519 faces against 83 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.
