LM4040DIZ-5.0

Texas Instruments · Voltage References · TO-92-3

LM4040DIZ-5.0 from Texas Instruments, in a TO-92-3. 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 * passive This pin must be left floating or connected to the anode; TI recommends connecting it to the anode in high-EMI or high-frequency switching-noise environments.
2 Cathode passive Shunt current input and reverse breakdown (output) voltage pin, 5V for this LM4040DIZ-5.0 version.
3 Anode power_in Anode pin, normally grounded.
