LM385Z-2.5 from Texas Instruments, in a TO-92. 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 | + | power_in | Cathode (+) terminal of the 2-terminal band-gap voltage reference; carries the operating current (20 µA to 20 mA) and is the terminal across which the 2.5V reverse breakdown reference voltage is developed. |
| 2 | - | power_in | Anode (-) terminal of the 2-terminal band-gap voltage reference, returned to circuit ground/common, completing the current path set by the external bias resistor. |
| 3 | NC | unconnected | No internal connection in the TO-92 package; shown isolated (open circle) in the bottom-view connection diagram and left floating. |
