REF3020AIDBZR

Texas Instruments · Voltage Reference · SOT-23

REF3020AIDBZR 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 input (V+). Operating range from (VREF + 1 mV) up to 5.5 V; a 0.47 uF bypass capacitor to GND is recommended. Absolute maximum V+ to V- is 7.0 V.
2 OUT output Regulated voltage reference output, 2.048 V nominal (2.044 to 2.052 V). Drives up to 25 mA; does not require an output capacitor, though a low-ESR cap of 10 uF or less may be used.
3 GND power_in Ground / common return (V-).

CAD (KiCad official)

  • Symbol: REF3020AIDBZR
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ref3020aidbzr-etched.step / ref3020aidbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ref3020aidbzr.step / ref3020aidbzr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ref3020aidbzr.step 59 KB You want the bare part, or you mark your own boards.
ref3020aidbzr-etched.step 2.3 MB You want the part with REF3020AIDBZR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 562 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.
