AS431ANTR-TP from TECH PUBLIC, in a SOT-23. 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. Compared internally to the 2.5V bandgap; the shunt regulator sinks cathode current when this pin exceeds Vref. Typical reference input current 0.7 uA (max 4 uA), max reference input current rating 10 mA. |
| 2 | CATHODE | power_in | Cathode (K). Shunt regulator output; sinks current from the load through an external series resistor to set the regulated node voltage. Continuous cathode current range 1 mA to 100 mA (absolute max -100 to +150 mA), Vka max 36 V. |
| 3 | ANODE | power_in | Anode (A). Reference/ground return for the shunt regulator; all voltages in the datasheet are referenced to this pin. |
