S-LTL431AKLT1G

LRC · Voltage Reference · SOT-23

S-LTL431AKLT1G from LRC, 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. Absolute maximum VKA = 40 V; continuous cathode current -100 mA to +150 mA. In a typical shunt-reference application the cathode is pulled up through a series resistor to Vi and forms the regulated node Vo.
2 REFERENCE input Reference (R) input to the internal error amplifier (compared against 2.5 V bandgap). Iref typ 0.5 uA (max 1.2 uA). Absolute maximum reference input current -0.05 mA to +10 mA. Output is regulated so that V(REF) = 2.495-2.500 V nominal.
3 ANODE passive Anode (A) terminal, the common/return of the shunt regulator. Typically connected to system ground in shunt-reference topologies.
