REF1004I-2.5 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | Not internally connected; the datasheet gives no function for this pin. |
| 2 | NC | unconnected | Not internally connected; the datasheet gives no function for this pin. |
| 3 | NC | unconnected | Not internally connected; the datasheet gives no function for this pin. |
| 4 | Anode | passive | Anode terminal of the two-terminal bandgap reference diode; the reference operates from 20µA minimum (REF1004-2.5) up to 20mA, with a forward current rating of 10mA and a reverse breakdown current rating of 30mA. |
| 5 | NC | unconnected | Not internally connected; the datasheet gives no function for this pin. |
| 6 | Cathode | passive | Cathode terminal of the two-terminal bandgap reference diode; the reference operates from 20µA minimum (REF1004-2.5) up to 20mA, with a forward current rating of 10mA and a reverse breakdown current rating of 30mA. |
| 7 | NC | unconnected | Not internally connected; the datasheet gives no function for this pin. |
| 8 | Cathode | passive | Cathode terminal of the two-terminal bandgap reference diode; the reference operates from 20µA minimum (REF1004-2.5) up to 20mA, with a forward current rating of 10mA and a reverse breakdown current rating of 30mA. |
