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 return (接地端). Connect to system ground. |+| 2 | LX | passive | Switch node (开关). Connects to the external boost inductor between VIN and the internal power switch / synchronous rectifier. Rated 1000 mA maximum switch current, 6.5 V absolute maximum. |+| 3 | VOUT | power_out | Regulated boost output (输出端), factory-set to 3.3 V ±2.5% (suffix '33'). Also serves as the IC supply once the output is above the input. Bypass with a 22 µF ceramic capacitor to GND. 6.5 V absolute maximum. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | NATLINEAR |+| Package | SOT-23-3L |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `XT1861B332MR-GM`+- `XT1861B332MR-GV`+- `XT1861B332MR-GS`+- `XT1861B332MR-GP`+- `XT1861B332MR-GL`+- `XT1861B332MR-GT`++## CAD (KiCad official)++- Symbol: `XT1861B332MR-G`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [NATLINEAR datasheet](docs/xt1861b332mr-g-datasheet.pdf) (13 pp, sha256 `e936a8c07359ec38`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
