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 1.24 V bandgap (VREF); the shunt turns on when V(REF) exceeds VREF, sinking cathode current. Reference input current typically 0.7 µA (max 4 µA). Set output with a resistor divider from CATHODE to ANODE feeding this pin: Vo = VREF(1 + R1/R2) + IREF·R1. |+| 2 | CATHODE | passive | Cathode (K) of the shunt regulator. Sinks the regulated current from the external series/ballast resistor RB. Absolute-max VKA = 18 V; continuous IKA range −100 to +150 mA; minimum cathode current for regulation ~55 µA (typ). Dynamic impedance ZKA ≈ 0.05 Ω (typ) at IK = 1-100 mA. |+| 3 | ANODE | passive | Anode (A) of the shunt regulator, the low-side / ground-referenced terminal. All voltages in the datasheet are referenced to the anode. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `AZ431LANTR-TP`++## CAD (KiCad official)++- Symbol: `AZ431LANTR-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/az431lantr-tp-datasheet.pdf) (5 pp, sha256 `c93ff2bf93303ecc`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
