TLVH431CDBZR 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 pin; connect external resistor divider between cathode and anode to program output voltage from 1.24V to 18V adjustable range |
| 2 | CATHODE | bidirectional | Cathode terminal providing regulated output voltage 1.24V to 18V via external programming resistor network; rated for continuous current 0.1mA to 70mA |
| 3 | ANODE | power_in | Anode (common/ground reference) terminal; serves as negative potential reference for device regulation, typically connected to circuit ground |
