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 / regulator reference return. On fixed-output AMS1117-x.x parts (including the 3.3 V variant) this pin is the device ground; on AMS1117-ADJ the same pin becomes the ADJ feedback input (VREF = 1.25 V nominal). Connect directly to the system ground plane. |+| 2 | VOUT | power_out | Regulated 3.3 V output, 0-800 mA. Requires at least a 22 µF tantalum output capacitor to ground for stability (smaller values acceptable on fixed versions per datasheet). The TO-220 metal tab is electrically connected to this pin (TAB is VOUT). |+| 3 | VIN | power_in | Unregulated input supply, absolute max 15 V, recommended operating up to 12 V. Requires ≥4.75 V for the 3.3 V variant to remain in regulation at full load (VDROP ≈ 1.2 V at 800 mA). A 10 µF bulk input capacitor to ground is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HANSCHIP semiconductor AMS1117T 3 3G |+| Package | TO-220-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `AMS1117T-3.3G`+- `AMS1117T-3.3GAMS1117-3.3RG`+- `AMS1117T-3.3GAMS1117-1.2RG`+- `AMS1117T-3.3GAMS1117-1.5RG`+- `AMS1117T-3.3GAMS1117-1.8RG`+- `AMS1117T-3.3GAMS1117-2.5RG`+- `AMS1117T-3.3GAMS1117-5.0RG`+- `AMS1117T-3.3GAMS1117-ADJRG`+- `AMS1117T-3.3GAMS1117PK-3.3RG`+- `AMS1117T-3.3GAMS1117PK-1.2RG`+- `AMS1117T-3.3GAMS1117PK-1.5RG`+- `AMS1117T-3.3GAMS1117PK-1.8RG`+- `AMS1117T-3.3GAMS1117PK-2.5RG`+- `AMS1117T-3.3GAMS1117PK-5.0RG`+- `AMS1117T-3.3GAMS1117PK-ADJRG`+- `AMS1117T-3.3GAMS1117KTP-3.3RG`+- `AMS1117T-3.3GAMS1117KTP-1.2RG`+- `AMS1117T-3.3GAMS1117KTP-1.5RG`+- `AMS1117T-3.3GAMS1117KTP-1.8RG`+- `AMS1117T-3.3GAMS1117KTP-2.5RG`+- `AMS1117T-3.3GAMS1117KTP-5.0RG`+- `AMS1117T-3.3GAMS1117KTP-ADJRG`+- `AMS1117T-3.3GAMS1117DT-3.3RG`+- `AMS1117T-3.3GAMS1117DT-1.2RG`+- `AMS1117T-3.3GAMS1117DT-1.5RG`+- `AMS1117T-3.3GAMS1117DT-1.8RG`+- `AMS1117T-3.3GAMS1117DT-2.5RG`+- `AMS1117T-3.3GAMS1117DT-5.0RG`+- `AMS1117T-3.3GAMS1117DT-ADJRG`+- `AMS1117T-3.3GAMS1117D-3.3RG`+- `AMS1117T-3.3GAMS1117D-3.3RG4`+- `AMS1117T-3.3GAMS1117D-1.2RG`+- `AMS1117T-3.3GAMS1117D-1.5RG`+- `AMS1117T-3.3GAMS1117D-1.8RG`+- `AMS1117T-3.3GAMS1117D-2.5RG`+- `AMS1117T-3.3GAMS1117D-5.0RG`+- `AMS1117T-3.3GAMS1117D-ADJRG`++## CAD (KiCad official)++- Symbol: `AMS1117T-3.3G`+- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`+- 3D model: TO-220-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HANSCHIP semiconductor AMS1117T 3 3G datasheet](docs/ams1117t-3-3g-datasheet.pdf) (12 pp, sha256 `eb1f648ce5a0d54d`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
