LM385M3X-1.2 from Texas Instruments, in a SOT-23. 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 | + | passive | Cathode (positive terminal) of the band-gap reference diode. Reverse-biased across an external current-limiting resistor; regulates to ~1.235 V with 10 µA-20 mA reverse current. |
| 2 | - | passive | Anode (negative / ground-side terminal) of the band-gap reference diode. |
| 3 | DAP | passive | Die Attach Pad. Per the connection diagram note, pin 3 should be connected to pin 2 (Anode) or left floating; it is not a functional signal terminal. |
