LM4041BIM3X-1.2 from Texas Instruments, 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 | - | bidirectional | Cathode (negative terminal). Carries the shunt current and produces the 1.225 V reference output voltage. Bias through a series resistor from the supply so that 60 μA ≤ I_R ≤ 12 mA. |
| 2 | + | power_in | Anode (positive/common terminal). Normally connected to ground (or to the low side of the reference network) and serves as the return path for the shunt current. |
| 3 | NC* | unconnected | No internal connection. Must be left floating or tied to the '+' (anode) pin. In high-EMI environments (transformer proximity or high-frequency switching noise) TI recommends tying this pin to the '+' pin. |
