TLVH431BQDBZRQ1 from Texas Instruments, in a SOT-23. 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 | REF | input | Reference input of the shunt regulator, which sets the cathode voltage via an external R1/R2 divider with VREF of 1.24 V and a reference current range of -0.05 mA to 3 mA. |
| 2 | CATHODE | passive | Cathode of the shunt regulator, which can be set from VREF to 18 V (20 V absolute maximum) and carries a continuous cathode current of 0.1 mA to 70 mA. |
| 3 | ANODE | power_in | Anode of the shunt regulator, normally tied to ground, with all cathode voltages specified with respect to this terminal. |
