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 (+) of the shunt voltage reference. Connect through a series resistor RS to the supply so that reverse current stays between IRMIN (45 µA typ, 65 µA max) and 15 mA. Regulates to VR = 2.5 V (±0.5%) with respect to ANODE. |+| 2 | ANODE | passive | Anode (−) of the shunt voltage reference. Normally tied to circuit ground; the 2.5 V reference voltage appears between CATHODE and this pin. |+| 3 | NC | passive | No internal connection to the reference circuit; pin is attached to the die substrate. Must be either left open or connected to ANODE - do not tie to CATHODE or to any other node. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `LM4040C25FTA-TPFTA-TP`++## CAD (KiCad official)++- Symbol: `LM4040C25FTA-TP`+- 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:** [TECH PUBLIC datasheet](docs/lm4040c25fta-tp-datasheet.pdf) (6 pp, sha256 `86174a00f4146ef3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
