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. Reverse breakdown pin held at the nominal reference voltage (2.5 V nom, 2.425-2.575 V over LM385-2.5 grade) when biased with 100 µA to 20 mA reverse current. |+| 2 | ANODE | passive | Anode (阳极) of the shunt voltage reference. Normally tied to circuit ground / return, with reverse bias current flowing from CATHODE to ANODE. |+| 3 | NC | unconnected | No internal connection (内部无连接). Leave floating or tie as convenient for PCB routing. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI LM385M3 2 5 TR |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `LM385M3-2.5/TR`+- `LM385M3-2.5LM385BM3-2.5/TR`+- `LM385M3-2.5LM385AM3-2.5/TR`+- `LM385M3-2.5LM385Z-2.5`+- `LM385M3-2.5LM385BZ-2.5`+- `LM385M3-2.5LM385AZ-2.5`+- `LM385M3-2.5LM385M-2.5/TR`+- `LM385M3-2.5LM385BM-2.5/TR`+- `LM385M3-2.5LM385AM-2.5/TR`+- `LM385M3-2.5LM385MM-2.5/TR`+- `LM385M3-2.5LM385BMM-2.5/TR`+- `LM385M3-2.5LM385AMM-2.5/TR`+- `LM385M3-2.5LM385DQ3-2.5/TR`+- `LM385M3-2.5LM385BDQ3-2.5/TR`+- `LM385M3-2.5LM385ADQ3-2.5/TR`+- `LM385M3-2.5LM385DQ2-2.5/TR`+- `LM385M3-2.5LM385BDQ2-2.5/TR`+- `LM385M3-2.5LM385ADQ2-2.5/TR`++## CAD (KiCad official)++- Symbol: `LM385M3-2.5`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI LM385M3 2 5 TR datasheet](docs/lm385m3-2-5-datasheet.pdf) (12 pp, sha256 `bb8ab21a5cf45a69`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
