LM4040CIM3X-2.5-TP

TECH PUBLIC · Voltage Reference · SOT-23

LM4040CIM3X-2.5-TP from TECH PUBLIC, 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 2.5V shunt reference, the reverse breakdown terminal; reverse current is rated 20 mA max and minimum operating current is 45 µA typ (65 µA max).
2 ANODE passive Anode (-) of the shunt reference, the ground-side terminal to which all voltages are referenced; forward current is rated 10 mA max.
3 NC unconnected Not connected internally but attached to the substrate, so it must be connected to ANODE or left open.
