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 2.495V bandgap; the device drives the CATHODE to sink whatever current is required to hold V(REF-ANODE) = Vref. Typical bias current 2µA (max 4µA at IKA = 10mA). Absolute max I_I(ref) range -0.05mA to 10mA. |+| 2 | CATHODE | bidirectional | Shunt current/voltage terminal. Sinks the regulated current from VKA=Vref up to 36V. Continuous IKA range -100mA to +150mA (abs max); recommended operating IKA 1mA to 100mA. Off-state leakage 0.1µA typ at VKA=36V, Vref=0. |+| 3 | ANODE | power_in | Common terminal, typically tied to ground/return. All voltages in the datasheet are referenced to ANODE unless noted otherwise. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-3 |+| Category | Power Management (PMIC) |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `TL432ACDBZT`+- `TL432ACDBZTDBZR`+- `TL432ACDBZTDBVT`+- `TL432ACDBZTDBVR`+- `TL432ACDBZTPK`++## CAD (KiCad official)++- Symbol: `TL432ACDBZT`+- 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:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/tl431) (None pp, sha256 `0eb18c491f5517a3`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
