LM4050BEM3X-2.5 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 | passive | Shunt current and input voltage pin; the reference regulates the voltage between cathode and anode according to the current supplied to the cathode, which must stay within the specified minimum (IRMIN) and the 15 mA maximum operating current. |
| 2 | Anode | passive | General-purpose pin that is normally grounded, and it must not exceed the 10 mA maximum forward current stated in the absolute maximum ratings. |
| 3 | NC | unconnected | No internal connection, but it must be left floating or connected to pin 2 (anode) because of a parasitic Schottky diode between pin 2 and the die attach contact in the SOT-23 package; TI recommends connecting it to the anode in high-EMI or high-frequency switching-noise applications. |
