AZ431BN-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 (feedback) input. Internally compared against the 2.500 V bandgap; drives the output transistor to hold this pin at Vref. Typical reference input current 0.7 uA (max 4.0 uA); max ±10 mA absolute. |
| 2 | CATHODE | passive | Cathode (K) of the shunt regulator. Sinks the regulation current from the load through an external bias resistor. Operating cathode current 1.0 mA to 100 mA (abs max -100 to +150 mA); Vka up to 36 V; dynamic impedance ~0.15 Ω typ. |
| 3 | ANODE | passive | Anode (A) of the shunt regulator; reference node for Vka and Vref. Typically tied to circuit ground/return. |
