# 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. |

## CAD (KiCad official)

- Symbol: `AZ1117H-1.2TRE1`
- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`
- 3D model: SOT-223-3 (KiCad packages3D, STEP)
- 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`](az1117h-1-2tre1.step) | 64 KB | You want the bare part, or you mark your own boards. |
| [`az1117h-1-2tre1-etched.step`](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.
