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. The internal error amplifier compares this pin against the 2.5V internal reference and modulates cathode sink current to hold REF at VREF (2.500V typ.). Typically driven by a resistor divider from CATHODE to ANODE to set the regulated cathode voltage (VKA = VREF·(1 + R1/R2) + IREF·R1). IREF ≈ 0.2µA typ. |+| 2 | ANODE | power_in | Anode / ground return. The device sinks cathode current through this pin; usually tied to circuit ground in shunt-regulator use. |+| 3 | CATHODE | power_in | Cathode / regulated node. Sinks 0.1 to 100mA (recommended operating range; -100 to +150mA absolute max) when the regulation loop is active. Cathode voltage range VREF to 36V (recommended); 40V absolute max. Off-state cathode current 0.05µA typ. at VKA = 36V with VREF = 0. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-89-3 |+| Category | Power Management (PMIC) |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `AP431SBRTR-G1ARTR-G1`+- `AP431SBRTR-G1HARTR-G1`+- `AP431SBRTR-G1`+- `AP431SBRTR-G1HBRTR-G1`+- `AP431SBRTR-G1ANTR-G1`+- `AP431SBRTR-G1AN1TR-G1`+- `AP431SBRTR-G1HANTR-G1`+- `AP431SBRTR-G1HAN1TR-G1`+- `AP431SBRTR-G1BNTR-G1`+- `AP431SBRTR-G1BN1TR-G1`+- `AP431SBRTR-G1HBNTR-G1`+- `AP431SBRTR-G1HBN1TR-G1`+- `AP431SBRTR-G1AZTR-G1`+- `AP431SBRTR-G1HAZTR-G1`+- `AP431SBRTR-G1BZTR-G1`+- `AP431SBRTR-G1HBZTR-G1`++## CAD (KiCad official)++- Symbol: `AP431SBRTR-G1`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8560102634330873856) (None pp, sha256 `770b9144c5e6fc10`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
