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 1.7V to 6.0V (absolute max -0.3 to 6.5V). Requires 1 uF ceramic input capacitor CIN. |+| 2 | VSS | power_in | Ground reference for the regulator. |+| 3 | CE | input | Chip Enable, active high. VCEH = 1.2V min to 6.0V max; VCEL = 0.3V max. XC6222D has internal CE pull-down resistor (ICEH typ 24 uA at 6.0V) and CL auto-discharge switch that discharges VOUT to VSS when CE is low. Stand-by current below 0.1 uA. |+| 4 | NC | unconnected | No connection. |+| 5 | VOUT | power_out | Regulated 3.3V output, 700mA max output current, 120mV dropout at 300mA. Requires a low-ESR ceramic output capacitor CL (2.2 uF or higher for VOUT 2.5-5.0V). Current limit typ 950 mA; short-circuit current typ 55 mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Torex Semicon |+| Package | SOT-25 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `XC6222D331MR-G`+- `XC6222D331MR-GER-G`+- `XC6222D331MR-GPR-G`++## CAD (KiCad official)++- Symbol: `XC6222D331MR-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/xc6222d331mr-g-datasheet.pdf) (24 pp, sha256 `4aa096bd159d1087`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
