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 | CATHODE | passive | Cathode (阴极) of the shunt voltage reference. In normal operation this pin sits at V_REF (nominal 1.235 V) above the anode when biased with 100 µA to 20 mA of reverse current. |+| 2 | ANODE | passive | Anode (阳极) of the shunt voltage reference. Typically tied to circuit ground / return; the reference voltage develops from cathode to anode. |+| 3 | NC | unconnected | No internal connection (内部无连接). Leave floating or tie to a convenient net; not electrically part of the reference. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI LM385M3 1 2 TR |+| Package | SOT-23-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `LM385M3-1.2/TR`+- `LM385M3-1.2LM385BM3-1.2/TR`+- `LM385M3-1.2LM385Z-1.2`+- `LM385M3-1.2LM385BZ-1.2`+- `LM385M3-1.2LM385M-1.2/TR`+- `LM385M3-1.2LM385BM-1.2/TR`+- `LM385M3-1.2LM385MM-1.2/TR`+- `LM385M3-1.2LM385BMM-1.2/TR`+- `LM385M3-1.2LM385DQ3-1.2/TR`+- `LM385M3-1.2LM385BDQ3-1.2/TR`+- `LM385M3-1.2LM385DQ2-1.2/TR`+- `LM385M3-1.2LM385BDQ2-1.2/TR`++## CAD (KiCad official)++- Symbol: `LM385M3-1.2`+- 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:** [HGSEMI LM385M3 1 2 TR datasheet](docs/lm385m3-1-2-datasheet.pdf) (12 pp, sha256 `bb8ab21a5cf45a69`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
