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. Sensing input to the internal error amplifier; regulates so that V(REF) equals the internal 2.495 V bandgap. Typical reference input current 1.5 μA (max 4 μA). |+| 2 | K | passive | Cathode. Shunt-regulator output terminal; sinks 1 to 100 mA in regulation with V(KA) ranging from V(REF) up to 36 V (absolute max 37 V). Off-state leakage typ 0.05 μA at V(KA)=36 V. |+| 3 | A | passive | Anode. Common/return terminal for the shunt regulator; typically tied to circuit ground in the reference-divider configuration. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | CBI |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `MMTL431MM`++## CAD (KiCad official)++- Symbol: `MMTL431M`+- 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:** [CBI datasheet](docs/mmtl431m-datasheet.pdf) (3 pp, sha256 `1daadd9e4fa3c494`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
