TLVH431BIDBZT 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 | Feedback input that sets the regulated voltage reference relative to anode, accepts reference current from -0.05 to 3mA. |
| 2 | CATHODE | bidirectional | Regulated output node and shunt current path, maintains voltage from 1.24V to 18V with maximum continuous shunt current of 70mA. |
| 3 | ANODE | power_in | Common return and reference ground connection with maximum 20V cathode voltage rating relative to this pin. |
