LM234DT from STMicroelectronics, in a SOIC-8. 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 | ADJ | input | Adjust pin. External current-set resistor (Rset) is connected between ADJ and V-; the voltage across Rset (~64 mV @ +25 °C) sets Iset. VADJ to V- absolute max is 5 V. |
| 2 | NC | unconnected | No internal connection. |
| 3 | NC | unconnected | No internal connection. |
| 4 | V+ | power_in | Positive supply / current input. Forward V+ to V- range 1 V to 40 V (LM234: 40 V max). Set current flows into this pin. |
| 5 | NC | unconnected | No internal connection. |
| 6 | V- | power_in | Negative supply / current output return. Set current flows out of this pin toward the load return. |
| 7 | NC | unconnected | No internal connection. |
| 8 | NC | unconnected | No internal connection. |

3D model downloads
Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
lm234dt.step |
122 KB | You want the bare part, or you mark your own boards. |
lm234dt-etched.step |
1.4 MB | You want the part with LM234DT already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 364 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
