LM4050AEM3-8.2 from Texas Instruments, in a SOT-23-3. 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 | Cathode | output | Reference voltage output cathode with operating current range from 60μA minimum to 15mA maximum. |
| 2 | Anode | power_in | Ground return anode terminal, common pin typically connected to ground. |
| 3 | NC | unconnected | No internal connection; parasitic Schottky diode exists between pin 3 and pin 2, so pin 3 must be left floating or connected to pin 2. |
