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 for the fixed 3.3V regulator. Connects to the negative side of the load; carries only the small quiescent current (typ 5 mA, max 10 mA). |+| 2 | VOUT | power_out | Regulated 3.3V output (3.235 V to 3.365 V over temperature) with 3A output current capability. Requires an output capacitor for stability (22µF tantalum or 150µF aluminum electrolytic recommended). Electrically shorted to the package tab. |+| 3 | VIN | power_in | Unregulated input supply, 4.75V to 12V for the -3.3 fixed variant (absolute max 15V). Dropout is 1.3V max at IOUT = 3A. Bypass with a local capacitor (e.g., 1µF tantalum) recommended. |+| TAB | VOUT | power_out | Metal tab is electrically connected to VOUT (pin 2) and serves as the primary thermal path. Solder to a copper pour (≥0.5 in² recommended) to achieve the specified θJA of 30°C/W. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Advanced Monolithic Systems AMS1085CM 3 3 |+| Package | TO-263-3 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++- `AMS1085CM-3.3`+- `AMS1085CM-3.3`+- `AMS1085CM-3.3AMS1085CT-3.3`+- `AMS1085CM-3.3AMS1085CD-3.3`++## CAD (KiCad official)++- Symbol: `AMS1085CM-3.3`+- Footprint: `Package_TO_SOT_SMD:TO-263-2`+- 3D model: TO-263-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Advanced Monolithic Systems AMS1085CM 3 3 datasheet](docs/ams1085cm-3-3-datasheet.pdf) (9 pp, sha256 `32e902e83fe32b68`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
