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 | VIN | power_in | Power input. Operating range 1.6V to 6.0V (absolute max VSS-0.3 to +6.5V). Bypass with a 1.0uF ceramic capacitor to VSS. |+| 2 | VSS | power_in | Ground reference for the regulator. |+| 3 | CE | input | Chip-enable ON/OFF control, active HIGH. VCEH >=1.2V (max 6.0V) enables the regulator; VCEL <=0.3V places the device in stand-by (<0.1uA). XC6221A has no internal pull-down, so leaving CE open is an undefined state, tie CE explicitly high or low. |+| 4 | NC | unconnected | No internal connection. May be left floating or tied to any potential. |+| 5 | VOUT | power_out | Regulated output. Fixed 1.8V nominal for the '182' option (Standard accuracy, +/-2% at Vout >= 1.50V). Rated 200mA (up to 250mA typ). Requires >=1.0uF ceramic stabilization capacitor (CL) to VSS. XC6221A has no CL auto-discharge, output decays through R1/R2 divider when disabled. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Torex Semicon |+| Package | SOT-25 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `XC6221A182MR-G`+- `XC6221A182MR-GGR`+- `XC6221A182MR-GGR-G`+- `XC6221A182MR-GNR`+- `XC6221A182MR-GNR-G`+- `XC6221A182MR-G7R-G`++## CAD (KiCad official)++- Symbol: `XC6221A182MR-G`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-25 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Torex Semicon datasheet](docs/xc6221a182mr-g-datasheet.pdf) (28 pp, sha256 `c5bad2e786b1d143`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
