REF2925AIDBZR

Texas Instruments · Voltage Reference · SOT-23

REF2925AIDBZR 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 IN power_in Input supply voltage. Operating range V_REF + 0.05 V to 5.5 V; absolute maximum 7 V. Powers the CMOS voltage reference core.
2 OUT output Reference output voltage. Nominal 2.5 V (2.45 V min, 2.55 V max) with 2% initial accuracy on the REF2925 variant. Sources up to 25 mA and is stable with any capacitive load.
3 GND power_in Ground return for the supply and reference output.

CAD (KiCad official)

  • Symbol: REF2925AIDBZR
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ref2925aidbzr-etched.step / ref2925aidbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ref2925aidbzr.step / ref2925aidbzr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ref2925aidbzr.step 59 KB You want the bare part, or you mark your own boards.
ref2925aidbzr-etched.step 2.2 MB You want the part with REF2925AIDBZR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 537 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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

  • Datasheet: Texas Instruments datasheet (29 pp, sha256 4b40ea3a2618d564, 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).
