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. Compared internally to the ~1.24V bandgap reference; used with an external resistor divider between CATHODE and ANODE to set the cathode voltage (Vka = Vref*(1+R1/R2) + Iref*R1). Reference input current typ 0.7µA, max 4µA. |+| 2 | CATHODE | passive | Cathode (K) of the shunt regulator. Sinks the regulation current; Vka rated to 18V max, continuous cathode current range 0.1mA to 100mA (abs max -100 to +150mA). Dynamic impedance 0.05Ω typ. |+| 3 | ANODE | passive | Anode (A) of the shunt regulator. All voltages in the datasheet are referenced to this pin; typically tied to the low-side of the feedback divider / ground return. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `TPTLV431BQDBZRDBZR`++## CAD (KiCad official)++- Symbol: `TPTLV431BQDBZR`+- 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/tptlv431bqdbzr-datasheet.pdf) (5 pp, sha256 `84693c4980b7f19d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
