TECH PUBLIC · Voltage Reference · SOT-23

TPTLV431BSN1T1G 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 to the internal error amplifier. The device drives the cathode current to hold this pin at VREF ≈ 1.24 V relative to the anode. Tied to the R1/R2 divider from cathode to anode to program the regulated output voltage VKA = VREF(1 + R1/R2) + IREF·R1. Reference input current is 0.7 µA typ (4 µA max); absolute maximum I(ref) is ±10 mA.
2 CATHODE input Cathode (K) of the shunt regulator. Sinks the regulated cathode current IKA (0.1-100 mA operating, ±150 mA absolute max) to hold the programmed voltage between cathode and anode. Absolute maximum VKA is 18 V; off-state cathode current is 0.01 µA typ at VKA = 6 V.
3 ANODE power_in Anode (A), the ground/return reference for the device. All internal voltages (VREF, VKA) are referenced to this pin per the datasheet convention. Typically tied to circuit ground in shunt-regulator use.
