Reverse current is drawn into this pin; regulated reference voltage (~1.235 V) appears between + and −. |+| 2 | - | passive | Negative (anode) terminal of the 1.235 V bandgap reference diode. Normally tied to circuit ground / return. |+| 3 | DAP | passive | Die Attach Pad (DAP). Not electrically part of the reference circuit; should be connected to Pin 2 (anode) or left floating. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XINLUDA XB385M3 1 2 |+| Package | SOT-23-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `XB385M3-1.2`+- `XB385M3-1.2XT285-1.2`+- `XB385M3-1.2XT385-1.2`+- `XB385M3-1.2XL285-1.2`+- `XB385M3-1.2XL385-1.2`++## CAD (KiCad official)++- Symbol: `XB385M3-1.2`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [XINLUDA XB385M3 1 2 datasheet](docs/xb385m3-1-2-datasheet.pdf) (12 pp, sha256 `8409d80bd41e2abd`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
