LM431SCCM3X-TP

TECH PUBLIC · Voltage Reference · SOT-23

LM431SCCM3X-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. Maximum cathode voltage VKA = 36 V; continuous cathode current range 1 mA to 100 mA (absolute max -100 to +150 mA). Sinks current to regulate the voltage between CATHODE and ANODE to VREF·(1+R1/R2).
2 REF input Reference input pin. Internal error amplifier compares this voltage against the internal 2.495 V bandgap reference (VREF, 2.483-2.507 V). Reference input current typically 0.7 µA (max 4.0 µA); absolute max reference input current 10 mA.
3 ANODE passive Anode (A) terminal of the shunt regulator, typically connected to ground / return. All voltage values in the datasheet are referenced to this pin.
