LM4041DIDBZT

Texas Instruments · Voltage Reference · SOT-23

LM4041DIDBZT 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 FB input Feedback pin for the adjustable output voltage, set by an external resistor divider to a value between 1.225V and 10V.
2 Cathode bidirectional Shunt current and output voltage; the external series resistor must limit cathode current to the 12mA maximum recommended rating.
3 Anode output Anode pin, normally grounded.

  • Symbol: LM4041DIDBZT
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: lm4041didbzt-etched.step / lm4041didbzt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm4041didbzt.step / lm4041didbzt.glb are the bare package body.
