LM4050AIM3-10

Texas Instruments · Voltage Reference · SOT-23-3

LM4050AIM3-10 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 bidirectional Cathode is the shunt-current and input-voltage pin; the reference voltage is regulated between cathode and anode as a function of the current forced into the cathode, which must stay within the minimum operating current (100 µA for the 10 V option) and the 15 mA maximum operating current.
2 Anode power_in Anode is the general-purpose pin, normally connected to ground, and is the reference terminal opposite the cathode; the datasheet notes a parasitic Schottky diode between pin 2 and pin 3 in this package.
3 NC unconnected No internal connection; this pin must be left floating or connected to pin 2 (anode), and TI recommends tying it to the anode in applications with high EMI or significant high-frequency switching noise.
