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. Compared internally to the 1.24V bandgap reference; when REF rises above Vref (~1.2400V, min 1.2214V / max 1.2586V at Ta=25°C) the device sinks current from cathode to anode. Reference input current is typically <1µA. |+| 2 | CATHODE | passive | Cathode (K). Shunt regulator output; sinks 0.1mA to 100mA in the on state. Maximum cathode voltage 18V; off-state leakage ~0.5µA at VKA=15V, VREF=0. Dynamic impedance ~0.5Ω at f≤1kHz. |+| 3 | ANODE | passive | Anode (A). Return terminal for the shunt current path; typically tied to circuit ground (or to the low side of the feedback divider in an adjustable-regulator configuration). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Jiangsu |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `CJ432 ±1%`+- 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:** [Jiangsu datasheet](docs/cj432-1-datasheet.pdf) (4 pp, sha256 `4298a1522dab0f25`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
