LM235Z from STMicroelectronics, in a TO-92-3. 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 | ADJ | passive | Optional calibration terminal; connecting a trim potentiometer here allows the output voltage to be adjusted (e.g., to 2.982V at 25°C) for higher accuracy per the single-point calibration method described in the Application information section. |
| 2 | V+ | power_in | Terminal of the 2-terminal Zener-type sensor through which the bias current (450µA to 5mA per the device description) is applied; the breakdown voltage measured relative to V- is directly proportional to absolute temperature at 10mV/°K. |
| 3 | V- | power_in | Return terminal of the 2-terminal Zener-type sensor, completing the current path set by the external bias resistor; dynamic impedance between V+ and V- is less than 1Ω. |
