TPTLVH431AIL3T

TECH PUBLIC · Voltage Reference · SOT-23

TPTLVH431AIL3T 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 1.24 V (typ) bandgap Vref; the shunt regulates the cathode-anode voltage so that REF = Vref. Set by an external R1/R2 divider from cathode: Vka = Vref*(1+R1/R2) + Iref*R1. Reference input current typ 0.7 uA, max 4.0 uA.
2 CATHODE input Cathode (K) of the shunt regulator. Sinks the regulated current from the load through an external ballast resistor; operating cathode current 0.1 mA to 100 mA, absolute max Vka = 18 V, Ika = -100 to +150 mA. Dynamic impedance 0.05 Ω typ (1 mA-100 mA, f<=1 kHz).
3 ANODE power_in Anode (A). Circuit common / ground return for the shunt reference; all voltages in the datasheet are referenced to the anode.
