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 pin for the fixed 1.8V regulator. Also used as the negative-side sense return for the internal Kelvin-connected output divider. |+| 2 | VOUT | power_out | Regulated 1.8V output (1.773V-1.827V typ at TJ=25°C). Requires at least 22µF solid tantalum output capacitor for stability. Rated up to 1A output current. |+| 3 | VIN | power_in | Unregulated supply input. Absolute maximum 15V. Requires (VIN - VOUT) ≥ ~1.1V dropout at 0.8A to maintain regulation; typical VIN for the 1.8V variant is 3.3V. |+| TAB | VOUT | power_out | Metal tab, electrically connected to VOUT. Serves as the primary thermal path (θJC = 15°C/W); solder to a copper pour to lower junction-to-ambient thermal resistance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Advanced Monolithic Systems |+| Package | TO-252 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `AMS1117CD-1.8`+- `AMS1117-1.8`+- `AMS1117CS-1.8`++## CAD (KiCad official)++- Symbol: `AMS1117CD-1.8`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Advanced Monolithic Systems datasheet](docs/ams1117cd-1-8-datasheet.pdf) (8 pp, sha256 `189a2651878a87d5`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
