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 (feedback) input. Internally compared against the 2.500 V bandgap; drives the output transistor to hold this pin at Vref. Typical reference input current 0.7 uA (max 4.0 uA); max ±10 mA absolute. |+| 2 | CATHODE | passive | Cathode (K) of the shunt regulator. Sinks the regulation current from the load through an external bias resistor. Operating cathode current 1.0 mA to 100 mA (abs max -100 to +150 mA); Vka up to 36 V; dynamic impedance ~0.15 Ω typ. |+| 3 | ANODE | passive | Anode (A) of the shunt regulator; reference node for Vka and Vref. Typically tied to circuit ground/return. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `AZ431BN-TP`++## CAD (KiCad official)++- Symbol: `AZ431BN-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/az431bn-tp-datasheet.pdf) (5 pp, sha256 `af258e73aec7d5cb`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
