TPNCP431AVSNT1G

TECH PUBLIC · Voltage Reference · SOT-23

TPNCP431AVSNT1G 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. Feedback node compared internally to the ~2.5 V bandgap; sets cathode voltage via external divider per V_KA = V_ref*(1+R1/R2)+I_ref*R1. Typical I_ref = 0.7 µA (max 4 µA).
2 CATHODE passive Cathode (K) terminal. Sinks the regulated current; V_KA adjustable from ~2.5 V to 36 V, continuous cathode current 1-100 mA, minimum for regulation 0.35 mA (typ). Off-state leakage 0.05 µA typ at V_KA = 12 V.
3 ANODE passive Anode (A) terminal. Common/ground return for the shunt regulator; all voltage values in the datasheet are referenced to the anode.
