TPTLV431IDBZR

TECH PUBLIC · Voltage Reference · SOT-23

TPTLV431IDBZR 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 to the internal error amplifier. Compared against the internal 1.24 V (typ) bandgap reference; drives the cathode shunt element to hold REF at Vref. Typically tied to the mid-point of an external resistor divider between CATHODE and ANODE to program the output voltage.
2 CATHODE passive Cathode (K) of the shunt regulator. Connected via a bias resistor to the supply; sinks 0.1-100 mA to regulate VKA from ~1.24 V up to 18 V. Presents ~0.05 Ω (typ) dynamic output impedance in the on-state.
3 ANODE passive Anode (A) return of the shunt regulator. Normally tied to circuit ground (or the low side of the programming divider); provides the common return for both the reference input and the cathode shunt current.
