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/threshold input. Internal error amplifier compares this pin's voltage to the internal 2.495 V bandgap reference. Typical Iref = 2 µA, max 4 µA (10 µA absolute max). Setting REF equal to Vref (2.495 V) with an external resistor divider between CATHODE and ANODE programs the regulated cathode voltage VKA = Vref × (1 + R1/R2). |+| 2 | CATHODE | passive | Shunt current/voltage input (K). Sinks 1 mA to 100 mA (150 mA absolute max) when the device is in regulation. VKA operates from Vref up to 36 V (37 V abs max). Off-state leakage typ 0.1 µA at VKA = 36 V, Vref = 0. Dynamic impedance |zKA| typ 0.2 Ω at f ≤ 1 kHz. |+| 3 | ANODE | passive | Common pin (A), normally connected to circuit ground / low side of the divider. All device voltages are referenced to ANODE unless otherwise stated. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `TL432AIDBZRIDBZR`+- `TL432AIDBZRIDBZT`+- `TL432AIDBZRIDBVR`+- `TL432AIDBZRIDBVT`+- `TL432AIDBZRIPK`++## CAD (KiCad official)++- Symbol: `TL432AIDBZR`+- 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/lit/ds/symlink/tl432aidbzr.pdf) (74 pp, sha256 `eefaeb640dec3168`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
