Threshold relative to the common anode; the device regulates the cathode voltage so REF equals VREF (typ 1.24 V). Reference terminal current is typically 0.15 uA. |+| 2 | CATHODE | bidirectional | Shunt current/voltage input (K). Sinks the regulated shunt current; recommended cathode current 0.1 mA to 15 mA, absolute max +/-20 mA, max cathode voltage 7 V. Typical dynamic impedance 0.25 ohm. |+| 3 | ANODE | power_in | Common terminal (A), normally connected to ground. All voltages in the datasheet are referenced to this terminal. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `TLV431AIDBZRIDBZR`+- `TLV431AIDBZRIDBZT`+- `TLV431AIDBZRIDBVR`+- `TLV431AIDBZRIDBVT`+- `TLV431AIDBZRIDCKR`+- `TLV431AIDBZRIDCKT`+- `TLV431AIDBZRID`+- `TLV431AIDBZRIDR`+- `TLV431AIDBZRIPK`+- `TLV431AIDBZRLP`+- `TLV431AIDBZRLPR`++## CAD (KiCad official)++- Symbol: `TLV431AIDBZR`+- 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:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tlv431aidbzr.pdf) (46 pp, sha256 `4c8a6bd9d4c66c01`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
