ref3033aidbzr.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 3 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

REF3033AIDBZR

Texas Instruments · Voltage Reference · SOT-23

REF3033AIDBZR 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 Supply voltage input (V+). Operating range VREF + 1mV (typ dropout) up to 5.5V; recommended VIN ≥ 3.35V for the 3.3V REF3033. Quiescent current 42µA typ / 50µA max.
2 OUT output Precision voltage reference output. 3.30V nominal (±0.2% initial accuracy, 3.294V-3.306V). Sources up to 25mA; stable without an external load capacitor. Short-circuit current typ 45mA to GND.
3 GND power_in Ground / common return (V−). Absolute maximum V+ to V− is 7.0V.

  • Symbol: REF3033AIDBZR
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ref3033aidbzr-etched.step / ref3033aidbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ref3033aidbzr.step / ref3033aidbzr.glb are the bare package body.

File Size Use it when
ref3033aidbzr.step 59 KB You want the bare part, or you mark your own boards.
ref3033aidbzr-etched.step 2.4 MB You want the part with REF3033AIDBZR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 584 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 (17 pp, sha256 ffa7c37e7b71c282, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
