TLV431BIDBVR from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection |
| 2 | SUBSTRATE | power_in | Substrate connection; must be connected to ANODE or left open |
| 3 | CATHODE | bidirectional | Shunt cathode output; regulated voltage from VREF (1.24V) to 6V with external resistor divider; cathode current 0.1 to 15 mA for regulation |
| 4 | REF | input | Reference feedback input; compared against internal 1.24V reference voltage with ±0.5% tolerance for TLV431B |
| 5 | ANODE | power_in | Anode common return; ground connection point normally connected to ground |
