TLVH431BQDBZR 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 voltage input pin; voltage is internally compared to 1.24 V reference and must maintain a minimum Iref of 0.5 µA over the operating temperature range of -40°C to +125°C for proper device operation |
| 2 | CATHODE | output | Shunt regulated output node; provides adjustable voltage from 1.24 V to 18 V relative to anode with continuous cathode current rating of 0.1 mA to 70 mA |
| 3 | ANODE | power_in | Common (ground) return pin and voltage reference point for cathode voltage measurements; SOT-23 package thermal resistance is 206 °C/W from junction to ambient |
