TLV431AIDBVR 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 any convenient net; the pin has no electrical function on TLV431/TLV431A in the DBV (SOT-23-5) package. |
| 2 | NC | unconnected | No internal connection on TLV431 and TLV431A (this pin is the substrate connection on TLV431B only, which must tie to ANODE or be left open). Safe to leave floating on TLV431A. |
| 3 | CATHODE | bidirectional | Shunt current/voltage input (K terminal). Sinks the regulated shunt current IK (0.1 mA to 15 mA recommended, 20 mA absolute max); VKA is regulated to VREF·(1+R1/R2) up to 6 V max. |
| 4 | REF | input | Reference input pin. Internally compared to the 1.24 V bandgap reference; connect to the R1/R2 divider tap between CATHODE and ANODE to set the regulated output voltage. Typical Iref = 0.15 µA (0.5 µA max). |
| 5 | ANODE | power_in | Common pin, normally connected to ground. All device voltages (VKA, VREF) are referenced to this terminal. |
