TLVH431QDCKR from Texas Instruments, in a SC-70-6. 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 | CATHODE | output | Shunt regulator cathode output where regulated voltage appears; voltage range 1.24 V to 18 V with cathode current from 0.1 mA to 70 mA |
| 2 | SUB | unconnected | Substrate connection, must be connected to ANODE or left open per datasheet |
| 3 | REF | input | Reference threshold input compared to internal 1.24 V ±1.5% reference, requires reference current of 0.1 µA to 0.5 µA |
| 4 | NC | unconnected | No internal connection |
| 5 | NC | unconnected | No internal connection |
| 6 | ANODE | power_in | Common return pin typically connected to ground; serves as current return path for shunt regulation |
