LM4040D30IDBZR

Texas Instruments · Voltage Reference · SOT-23

LM4040D30IDBZR from Texas Instruments, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CATHODE passive Shunt current/voltage input (cathode of the reference). Regulates to 3.0 V above the anode when biased through a series resistor RS. Recommended cathode current 45 µA to 15 mA.
2 ANODE passive Common pin, normally connected to ground. Return path for the shunt current.
3 SUB passive Substrate connection. Pin 3 is attached to substrate and must be connected to ANODE or left open.

CAD (KiCad official)

  • Symbol: LM4040D30IDBZR
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: lm4040d30idbzr-etched.step / lm4040d30idbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm4040d30idbzr.step / lm4040d30idbzr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (60 pp, sha256 9969399d53c90478, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
