LM4040C50IDCKR 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 | Ground and return terminal of the parallel shunt voltage reference circuit. |
| 2 | * | passive | Optional substrate guard pin; must be left floating or connected to anode for electromagnetic interference suppression in high-noise environments. |
| 3 | CATHODE | output | Precision reference voltage output; provides 5V ±25mV (±0.5%) at IZ = 100μA and 25°C, with 100ppm/°C temperature coefficient over -40°C to 85°C. |
| 4 | NC | unconnected | No internal connection; leave unconnected or tie to anode. |
| 5 | NC | unconnected | No internal connection; leave unconnected or tie to anode. |
