LM4040DIM3-2.5+T

Analog Devices Inc Maxim Integrated · Voltage Reference · SOT-23

LM4040DIM3-2.5+T from Analog Devices Inc Maxim Integrated, 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 + passive Positive (cathode) terminal of the shunt reference. Connect through a source resistor RS to the supply; the device regulates VR = 2.500V across pins 1 (+) and 2 (-). Reverse current must be kept between IRMIN (~65µA typ, 70µA max for D-grade) and 15mA for regulation, and must never exceed 20mA absolute maximum.
2 - passive Negative (anode) terminal of the shunt reference. Typically tied to circuit ground; forward current from anode to cathode must not exceed 10mA absolute maximum.
3 N.C. unconnected No internal connection. Must be left unconnected or tied to pin 2 (negative terminal); do not connect to any other node.
