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. |
