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 1.24 V (typ) bandgap reference; the device sinks cathode current to regulate this pin to Vref. Reference input current is 0.7 µA typ (4 µA max); absolute max input current 10 mA. |+| 2 | CATHODE | input | Cathode (Vka). Shunt-regulator current-sink terminal; connects through a series resistor RB to the supply rail. Absolute maximum Vka = 18 V; continuous cathode current range 0.1 mA to 100 mA (abs max −100 to +150 mA). Dynamic impedance 0.05 Ω typ. |+| 3 | ANODE | power_in | Anode. Ground / return terminal for the shunt regulator; all voltages in the datasheet are referenced to this pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `TP432R124S3`++## CAD (KiCad official)++- Symbol: `TP432R124S3`+- 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/tp432r124s3-datasheet.pdf) (5 pp, sha256 `41280134c062bf39`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
