TS2431AILT-TP

TECH PUBLIC · Voltage Reference · SOT-23

TS2431AILT-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 CATHODE passive Cathode (K) terminal of the shunt regulator. Sinks the regulated cathode current I_KA (1-100 mA operating; 150 mA abs max) at V_KA up to 36 V. Tied to the output node through a series ballast resistor R_B in typical shunt/series regulator topologies.
2 REF input Reference (feedback) input. Internal error amplifier drives the cathode current to force V(REF) = V_ref = 2.500 V (typ) relative to ANODE. Reference input current I_REF is 0.7 uA typ (4 uA max); connect to the R1/R2 divider that sets V_KA = V_ref*(1 + R1/R2) + I_REF*R1.
3 ANODE passive Anode (A) terminal, the ground/return of the shunt regulator. All voltage values (V_KA, V_REF) are referenced to this pin.
