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/GND | power_in | Ground / adjust pin. On the fixed-voltage AMS1117-3.3 this pin is the device ground reference (0 V return). On adjustable versions it is the ADJ feedback tap to an external divider. |+| 2 | VOUT | power_out | Regulated 3.3 V output (typ. 3.300 V, min 3.235 V, max 3.365 V over 0≤IOUT≤800 mA, 4.75 V≤VIN≤10 V). Requires ≥22 µF tantalum output capacitor on adjustable version; smaller cap acceptable for fixed version. |+| 3 | VOUT | power_out | Regulated 3.3 V output (paralleled with pin 2, 6, 7). Multiple VOUT pins on SOP-8L reduce lead resistance and improve heat dissipation at 800 mA. |+| 4 | VIN | power_in | Unregulated input supply voltage. Absolute max 15 V; recommended operating VIN ≤ 12 V. Requires ≥10 µF bulk input capacitor. Dropout is typ. 1.2 V at 800 mA (VIN must be ≥ VOUT + Vdrop). |+| 5 | N/C | unconnected | No internal connection. Leave floating or tie to GND per PCB layout preference. |+| 6 | VOUT | power_out | Regulated 3.3 V output (paralleled with pins 2, 3, 7). |+| 7 | VOUT | power_out | Regulated 3.3 V output (paralleled with pins 2, 3, 6). |+| 8 | N/C | unconnected | No internal connection. Leave floating or tie to GND per PCB layout preference. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HANSCHIP semiconductor AMS1117M 3 3RG |+| Package | SOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `AMS1117M-3.3RG`+- `AMS1117M-3.3RGD-3.3RG`+- `AMS1117M-3.3RGMK-3.3RG`+- `AMS1117M-3.3RGT-3.3G`+- `AMS1117M-3.3RGMDT-3.3RG`+- `AMS1117M-3.3RGDT-3.3RG`++## CAD (KiCad official)++- Symbol: `AMS1117M-3.3RG`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HANSCHIP semiconductor AMS1117M 3 3RG datasheet](docs/ams1117m-3-3rg-datasheet.pdf) (None pp, sha256 `d10dc13d6474e5e2`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
