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 | R | input | Reference input. Internal error amplifier compares this pin against the 1.25 V band-gap reference; when V(R) exceeds Vref the device sinks current from cathode to anode. Reference input current Iref is typically 1.5 uA (max 4 uA); maximum reference input current rating is 6 mA. |+| 2 | K | passive | Cathode. Programmable shunt terminal; sinks current to the anode to regulate V(KA) to the set point defined by the external divider (VKA = Vref (1 + R1/R2) + Iref x R1). Maximum cathode voltage 18 V, continuous cathode current 100 mA, dynamic impedance typ 0.15 ohm. |+| 3 | A | passive | Anode. Common return terminal, typically tied to circuit ground/negative supply of the shunt reference. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-23-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `TL432 0.5%UMW TL432 0.5%`++## CAD (KiCad official)++- Symbol: `TL432 0.5%`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/tl432-0-5-datasheet.pdf) (7 pp, sha256 `3e3595dac7d171a8`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
