Regulates the cathode current so that this pin sits at VREF (2.495V typ) with respect to the anode. Typical reference input current 0.2µA, max 0.5µA. |+| 2 | CATHODE | passive | Cathode of the shunt regulator; sinks current from an external pull-up when VREF pin rises above the internal reference. Continuous cathode current range -100 to 150 mA; recommended operating cathode current 0.1 to 100 mA; absolute-max cathode voltage 40V (36V recommended). |+| 3 | ANODE | passive | Anode of the shunt regulator; the common return for cathode current and the reference-voltage return. Typically tied to circuit ground in shunt-regulator applications. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `AP431SHANTR-G1`+- `AP431SANTR-G1`+- `AP431SBNTR-G1`+- `AP431SHBNTR-G1`+- `AP431SAN1TR-G1`+- `AP431SHAN1TR-G1`+- `AP431SBN1TR-G1`+- `AP431SHBN1TR-G1`+- `AP431SARTR-G1`+- `AP431SHARTR-G1`+- `AP431SBRTR-G1`+- `AP431SHBRTR-G1`+- `AP431SAZTR-G1`+- `AP431SHAZTR-G1`+- `AP431SBZTR-G1`+- `AP431SHBZTR-G1`++## CAD (KiCad official)++- Symbol: `AP431SHANTR-G1`+- 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:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/AP431SHANTR-G1.pdf) (17 pp, sha256 `770b9144c5e6fc10`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
