TL432ASC

PJSEMI · Voltage Reference · SOT-23-3

TL432ASC from PJSEMI, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 REF input Reference input of the 1.25 V bandgap; the datasheet gives an absolute maximum reference input current of 10 mA and a reference input voltage of 1.238 V to 1.262 V for the 1% (TL432A) grade.
2 Cathode passive Cathode of the shunt regulator, with a recommended operating range of VREF to 18 V and recommended cathode current of 0.1 mA to 100 mA; the absolute maximum cathode current is -100 mA to +100 mA.
3 Anode passive Common anode terminal to which the cathode voltage VKA and cathode current IKA are referenced; the datasheet states no separate anode voltage or current limit.
