# AZ1117CH-5.0TRG1

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

AZ1117CH-5.0TRG1 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. On the fixed-voltage AZ1117CH-5.0 the ADJ/GND pin functions as the device ground return. |
| 2 | VOUT | power_out | Regulated 5.0V output (typ 5.0V, ±1%). Requires a minimum 10µF output capacitor with ESR < 20Ω for stability; supplies up to ~1A load current within the current-limit of 1.35A typical. |
| 3 | VIN | power_in | Unregulated input supply. Recommended operating input voltage up to 15V (18V absolute max). Requires at least VOUT + VDROP (typ 1.2V @ 0.8A) headroom. |
| 4 | VOUT | power_out | Tab / heat-slug pad, electrically connected to VOUT (pin 2). Provides the primary thermal path; solder to a copper pour for heat sinking (θJA ≈ 125°C/W without heatsink for SOT-223). |

## CAD (KiCad official)

- Symbol: `AZ1117CH-5.0TRG1`
- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`
- 3D model: SOT-223 (KiCad packages3D, STEP)
- 3D model files: `az1117ch-5-0trg1-etched.step` / `az1117ch-5-0trg1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `az1117ch-5-0trg1.step` / `az1117ch-5-0trg1.glb` are the bare package body.

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`az1117ch-5-0trg1.step`](az1117ch-5-0trg1.step) | 64 KB | You want the bare part, or you mark your own boards. |
| [`az1117ch-5-0trg1-etched.step`](az1117ch-5-0trg1-etched.step) | 2.1 MB | You want the part with `AZ1117CH-5.0TRG1` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 539 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.
