LM4051CIM3X-1.2

Texas Instruments · Voltage Reference · SOT-23-3

LM4051CIM3X-1.2 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 bidirectional Parallel current/voltage input; a series resistor RS from the supply sets the reverse current IR, which must stay between IRMIN (60 µA industrial) and IRMAX (12 mA).
2 Anode output General-purpose pin, normally tied to ground, and the reference return for the shunt device.
3 NC unconnected Must be left floating or connected to the anode (pin 2); TI recommends connecting it to the anode in high-EMI or high-frequency switching-noise environments.
