LM4050QBEM3X2.5
Texas Instruments · Voltage Reference · SOT-23
LM4050QBEM3X2.5 from Texas Instruments, in a SOT-23. 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 | bidirectional | Shunt current and input voltage pin; the cathode current must stay at or above the minimum operating current (IRMIN) and below the 15 mA maximum operating current for the reference to regulate. |
| 2 | Anode | output | General-purpose pin, usually grounded; in SOT-23 packages it has a parasitic Schottky diode to pin 3 that is why pin 3 must be left floating or tied to this pin. |
| 3 | NC | unconnected | No internal connection; it must be left floating or connected to pin 2, and TI recommends connecting it to the anode in applications with high EMI or significant high-frequency switching noise. |
