LTL431APTLT1G

LRC · Voltage Reference · SOT-23

LTL431APTLT1G from LRC, in a SOT-23. 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 CATHODE passive Cathode of the programmable shunt regulator; the output voltage is set by the external divider on the REF pin, and the cathode current must stay within the datasheet limits to keep the device in regulation.
2 REF input Reference input pin that regulates to the internal reference voltage (Vref, 2.470 V to 2.525 V depending on the grade), with a reference input current of about 4 µA at 25 °C.
3 ANODE passive Anode of the shunt regulator, the common return for the cathode current, which the datasheet states must be held at the anode reference for the specified electrical characteristics.
