LM4050QCIM3-4.1

Texas Instruments · Voltage Reference · SOT-23

LM4050QCIM3-4.1 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 passive Shunt current and input voltage pin; the regulated voltage between cathode and anode depends on the current fed to the cathode, which must stay within the minimum operating current (IRMIN) and the 15 mA maximum for the selected version.
2 Anode passive General-purpose pin that is normally grounded and serves as the reference return for the cathode voltage; the datasheet notes a parasitic Schottky diode between this pin and pin 3.
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.
