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 | REF | input | Reference input pin. Internal error amplifier compares this pin to the internal 1.24 V bandgap and adjusts cathode conduction to hold REF at Vref. Reference input current is typ 0.7 uA (max 4.0 uA); absolute maximum reference input current 10 mA. |+| 2 | CATHODE | power_in | Cathode (K) of the shunt regulator. Sinks continuous current in the range 0.1-100 mA (abs max -100 to +150 mA) to hold Vka at the programmed voltage. Vka absolute maximum 18 V; dynamic impedance 0.05 Ω typ. |+| 3 | ANODE | power_in | Anode (A) of the shunt regulator, common return for all voltages in the device (datasheet notes all voltages are referenced to the anode). Connect to circuit ground for standard shunt-reference use. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `TLV431BFTA-TPTA-TP`++## CAD (KiCad official)++- Symbol: `TLV431BFTA-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/tlv431bfta-tp-datasheet.pdf) (5 pp, sha256 `47f6772176fde823`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
