TLV431ACDBVR from Texas Instruments, in a SOT-23-5. 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 | NC | unconnected | No internal connection. Leave floating or tie to a convenient net. |
| 2 | NC | unconnected | No internal connection for TLV431 and TLV431A grades. (On TLV431B this pin is a substrate connection that must be tied to ANODE or left open.) Since this part is TLV431A, treat as NC. |
| 3 | CATHODE | passive | Shunt current/voltage input (K). Sinks the regulator current; VKA operating range VREF (1.24 V) to 6 V. Absolute max VKA = 7 V; continuous cathode current range -20 to 20 mA; recommended IK 0.1 to 15 mA. Dynamic impedance typ 0.25 Ω. |
| 4 | REF | input | Reference input threshold pin relative to common ANODE. Internal bandgap regulates so VREF = 1.24 V nom (1.21 V min / 1.27 V max at 25°C for TLV431A). Reference terminal current typ 0.15 µA (max 0.5 µA). |
| 5 | ANODE | passive | Common anode pin (A), normally connected to ground / circuit common. All voltages referenced to this pin. |
