AN431BN-ATRG1

Diodes Incorporated · Voltage Reference · SOT-23

AN431BN-ATRG1 from Diodes Incorporated, 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 CATHODE passive Cathode (K) terminal of the shunt regulator. Sinks the regulated current when VREF pin reaches the internal 2.5 V reference. Operating cathode voltage 2.5 V to 36 V; cathode current 1 mA to 100 mA; absolute max VKA = 40 V.
2 REF input Reference input pin. Regulates the cathode so that VREF equals the internal 2.5 V bandgap. Typical reference input current 0.7 μA (max 4 μA); absolute max IREF = 10 mA.
3 ANODE passive Anode (A) terminal, the current return of the shunt regulator, typically tied to circuit ground in the standard divider-programmed shunt topology.
