Regulates to VR = 2.5 V (±0.5%) above the anode when biased through an external series resistor RS. Reverse current range IRMIN = 45 µA to IR(max) = 20 mA; forward current limit 10 mA. |+| 2 | ANODE | passive | Anode (−) of the shunt voltage reference; typically tied to circuit ground/return. All voltage values in the datasheet are referenced to this pin. |+| 3 | NC | unconnected | No internal connection to the reference circuit; pin is attached to the die substrate and must be connected to ANODE or left open. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `TP4040C25S3`++## CAD (KiCad official)++- Symbol: `TP4040C25S3`+- 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/tp4040c25s3-datasheet.pdf) (6 pp, sha256 `f9ce38855720d349`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
