REF3325AIDBZR

Texas Instruments · Voltage Reference · SOT-23

REF3325AIDBZR 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 VOUT + 0.2 V to 5.5 V (absolute max 7.5 V). Typical quiescent current 3.9 uA. Bypass with a capacitor to GND per power-supply recommendations.
2 OUT power_out Reference output voltage, 2.5 V nominal (REF3325). Sources and sinks up to +/-5 mA within specified accuracy; short-circuit current 35 mA typ, 180 mA abs max. Stable with capacitive loads from 0.1 uF to 10 uF.
3 GND power_in Device ground reference. Connect to the system analog ground plane.

CAD (KiCad official)

  • Symbol: REF3325AIDBZR
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ref3325aidbzr-etched.step / ref3325aidbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ref3325aidbzr.step / ref3325aidbzr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ref3325aidbzr.step 59 KB You want the bare part, or you mark your own boards.
ref3325aidbzr-etched.step 2.3 MB You want the part with REF3325AIDBZR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 560 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 (37 pp, sha256 5d03199eb5b4e1cc, 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).
