LM4040DELT-2.0

STMicroelectronics · Voltage Reference · SOT-23-3L

LM4040DELT-2.0 from STMicroelectronics, in a SOT-23-3L. 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 K passive Cathode of the shunt reference, where the 2.048 V reverse breakdown voltage appears; operating current is 10 µA minimum to 15 mA maximum.
2 A passive Anode of the shunt reference, connected to circuit ground.
3 NC unconnected No connect; must be left unconnected or connected to anode.
