TLVH431AIL3T from STMicroelectronics, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | REF | input | Reference input; external resistor divider sets the adjustable output (shunt) voltage from 1.24 V to 18 V; typical reference input current is 1.5 µA (2.5 µA max) with R1=10 kΩ, R2=∞. |
| 2 | CATHODE | passive | Cathode (K) terminal of the shunt regulator; sinks the regulated current from 100 µA min to 60 mA max, with cathode-to-anode voltage from Vref up to 18 V. |
| 3 | ANODE | power_in | Anode (A) terminal, the low-side/ground reference of the shunt regulator against which the cathode-to-anode voltage (VKA, up to 22 V absolute max) is measured. |
