LM4040EIM7-2.0 from Texas Instruments, in a SC-70-5. 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 | Anode | power_in | Positive/anode terminal of the shunt voltage reference; per Table 4-1 it is normally connected to ground and forms the common/return node for the reverse (shunt) current. |
| 2 | * | passive | Internally tied to the die-attach pad; must be left floating or connected to Pin 1 (Anode). TI recommends tying it to the anode in applications with high EMI or significant high-frequency switching noise. |
| 3 | Cathode | power_out | Negative/cathode terminal that carries the shunt (reverse) operating current IR and presents the regulated reverse breakdown/output voltage (nominal 2.048V for the -2.0 option, IR between IRMIN and 15mA). |
| 4 | NC | unconnected | No internal connection. |
| 5 | NC | unconnected | No internal connection. |
