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 return for the regulator. On fixed-output versions (including the -3.3 variant) this pin is the device ground; the datasheet labels it GND/ADJ because the same pinout serves as ADJ on the adjustable version. |+| 2 | VOUT | power_out | Regulated 3.3V output pin (typ. 3.234V-3.366V at IOUT=10mA, VIN=5V). Requires an output capacitor (22µF tantalum recommended) for stability. Rated for up to 1A continuous load, limited by thermal dissipation. |+| 3 | VIN | power_in | Unregulated input supply (absolute max 18V; recommended operating input 12V). Should be bypassed with a 10µF capacitor close to the pin. Must be at least VOUT + VDROP (~1.2V @ 1A) above the target 3.3V output. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Unknown |+| Package | TO-252-2 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `AMS1117CD-3.3CD-3.3`+- `AMS1117CD-3.3CD`+- `AMS1117CD-3.3-3.3`+- `AMS1117CD-3.3-1.2`+- `AMS1117CD-3.3-1.5`+- `AMS1117CD-3.3-1.8`+- `AMS1117CD-3.3-2.5`+- `AMS1117CD-3.3-5.0`+- `AMS1117CD-3.3-ADJ`+- `AMS1117CD-3.3S-3.3`+- `AMS1117CD-3.3S`++## CAD (KiCad official)++- Symbol: `AMS1117CD-3.3`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252-2 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Unknown datasheet](docs/ams1117cd-3-3-datasheet.pdf) (13 pp, sha256 `5ec219092aa45bd9`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
