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. Connected to the internal comparator input; the device regulates the cathode voltage such that Vref (typ. 1.2400 V, guaranteed 1.2214-1.2586 V) appears between REF and ANODE. Reference input current is ~0.6 µA (max drift over temperature) with 6 µA absolute max. |+| 2 | CATHODE | power_in | Cathode (K) terminal of the shunt regulator. Sinks current from the load; operating cathode voltage range up to VKA = 18 V max, continuous cathode current up to 100 mA, minimum cathode current for regulation 0.1 mA. Dynamic impedance ~0.5 Ω at f ≤ 1 kHz. |+| 3 | ANODE | power_in | Anode (A) terminal, typically connected to circuit ground/common. Serves as the return path for cathode sink current and the reference voltage return. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | CBI |+| Package | SOT-23-3L |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `MMTL432`++## CAD (KiCad official)++- Symbol: `MMTL432`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [CBI datasheet](docs/mmtl432-datasheet.pdf) (5 pp, sha256 `cb6dcff353cf17ee`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
