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. On the fixed 3.3V version this pin is the device ground return; the internal voltage divider references this pin. |+| 2 | VOUT | power_out | Regulated 3.3V output pin (typical 3.30V, min 3.234V, max 3.366V). Requires a minimum 10uF tantalum capacitor to GND (ESR ≤ 0.5Ω) for compensation and stability. Capable of sourcing up to 1A. |+| 3 | VIN | power_in | Unregulated input voltage pin. Maximum input voltage 30V; requires at least VOUT + 1.3V (dropout) for regulation. A 10uF tantalum input bypass capacitor is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | JSMSEMI AMS1117S 3 3 |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `AMS1117S-3.3`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [JSMSEMI AMS1117S 3 3 datasheet](docs/ams1117s-3-3-datasheet.pdf) (9 pp, sha256 `fa4bc29b88340b9a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
