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 | INPUT | power_in | Unregulated input supply. Absolute max 18 V; recommended operating max 15 V. Requires a 10 µF (or larger) bypass capacitor to GND close to the pin for stability. |+| 2 | ADJ/GND | power_in | Ground reference on the fixed-voltage AZ1117C-5.0 version (ADJ pin is internally tied to GND on fixed variants). Serves as the return for both the input bypass and output capacitors. |+| 3 | OUTPUT | power_out | Regulated 5.0 V output (±1% at 25 °C, ±2% over -20 to +125 °C). Current limit 1.35 A typ. Requires a minimum 22 µF (ESR < 20 Ω) ceramic output capacitor for stability. |+| 4 | ADJ/GND | power_in | SOT-223 thermal tab, electrically connected to the ADJ/GND pin. On fixed 5.0 V version this is GND; solder to a copper pour to improve θJA (≈125 °C/W without heatsink, 100 °C/W with heatsink for SOT223). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated AZ1117CH2 5 0TRG1 |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `AZ1117CH2-5.0TRG1H2`+- `AZ1117CH2-5.0TRG1H`+- `AZ1117CH2-5.0TRG1D`+- `AZ1117CH2-5.0TRG1CJ`+- `AZ1117CH2-5.0TRG1R`+- `AZ1117CH2-5.0TRG1R2`++## CAD (KiCad official)++- Symbol: `AZ1117CH2-5.0TRG1`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated AZ1117CH2 5 0TRG1 datasheet](docs/az1117ch2-5-0trg1-datasheet.pdf) (24 pp, sha256 `8333717aa7b5f90f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
