REF5025AIDR

Texas Instruments · Voltage Reference · SOIC-8

REF5025AIDR from Texas Instruments, in a SOIC-8. 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 DNC unconnected Do not connect. Leave this pin electrically open; do not tie to any other node.
2 VIN power_in Input supply voltage. Must be at least VOUT + 0.2 V (except REF5020 min = 2.7 V); absolute max 18 V. Bypass with 1 µF to GND.
3 TEMP output Temperature monitoring output. Provides a temperature-dependent voltage suitable for solder heat-shift monitoring or ambient sensing.
4 GND power_in Device ground reference for supply and output.
5 TRIM/NR input Output-voltage trim and noise-reduction pin. Used to fine-tune VOUT and/or add a capacitor for noise reduction on the reference output.
6 VOUT power_out Precision reference voltage output. Nominal 2.5 V for REF5025; can source and sink up to ±10 mA. Bypass with 1 µF to GND.
7 NC unconnected No internal connection. May be left floating or tied to any potential without affecting device operation.
8 DNC unconnected Do not connect. Leave this pin electrically open; do not tie to any other node.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ref5025aidr.step 122 KB You want the bare part, or you mark your own boards.
ref5025aidr-etched.step 2.2 MB You want the part with REF5025AIDR 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 147 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 (38 pp, sha256 3a575c2957f81ba6, 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).
