TLVH431AQDBZR 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 threshold pin for voltage feedback; external resistor divider network sets regulated output voltage from 1.24V to 18V; requires minimum input current of 0.1 μA to 0.5 μA typical for proper amplifier operation. |
| 2 | CATHODE | bidirectional | Shunt regulator cathode output pin; sinks continuous current from 0.1 mA to 70 mA for output voltage regulation from 1.24V to 18V with typical dynamic impedance of 0.25 Ω. |
| 3 | ANODE | power_in | Anode ground common return pin; reference terminal for all shunt current, normally connected to ground or negative supply rail. |
