LM4040AIM3X-10

Texas Instruments · Voltage Reference · SOT-23-3

LM4040AIM3X-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 passive Shunt current/output voltage pin (10V reverse breakdown for this part), operating with reverse current from 100μA to 15mA.
2 Anode passive Anode pin, normally connected to ground.
3 * passive Must be left floating or connected to pin 2 (anode); TI recommends connecting it to the anode in high-EMI or high-frequency-switching-noise applications because of a parasitic Schottky diode between pins 2 and 3.
