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 | ADJ | input | Adjust pin. Connect to the mid-point of an external resistor divider between VOUT and GND to set the output voltage per VOUT = VREF x (1 + R2/R1) + IADJ x R2, where VREF = 1.25V typical and IADJ = 60 uA typical (120 uA max). |+| 2 | VOUT | power_out | Regulated output voltage. Requires an output capacitor for stability (22 uF tantalum recommended). Rated for 1A continuous output current. |+| 3 | VIN | power_in | Input supply voltage. Absolute maximum 18V; recommended operating input up to 12V. A 10 uF input capacitor is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `AMS1117-ADJADJ`+- `AMS1117-ADJCD-ADJ`+- `AMS1117-ADJS-ADJ`++## CAD (KiCad official)++- Symbol: `AMS1117-ADJ`+- 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:** [UMW datasheet](docs/ams1117-adj-datasheet.pdf) (13 pp, sha256 `5ec219092aa45bd9`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
