RS5025XK

Jiangsu RUNIC Tech · Voltage Reference · SOIC-8

RS5025XK from Jiangsu RUNIC Tech, 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. This pin must be left floating; do not tie to any signal, supply, or ground.
2 VIN power_in Input supply voltage. Powers the internal reference core; bypass with a 1 µF ceramic capacitor to GND close to the pin.
3 NC unconnected No internal connection. May be left floating or tied to GND.
4 GND power_in Ground return for the reference. Connect to the system analog ground plane.
5 NC unconnected No internal connection. May be left floating or tied to GND.
6 VOUT output Reference voltage output (2.5 V nominal for RS5025). Can source or sink up to ±10 mA; bypass to GND with 1 µF for stability and noise filtering.
7 NC unconnected No internal connection. May be left floating or tied to GND.
8 DNC unconnected Do not connect. This pin must be left floating; do not tie to any signal, supply, or ground.

Ordering variants

Same part, different packaging or reel option.

  • RS5025XK

CAD (KiCad official)

  • Symbol: RS5025XK
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: rs5025xk-etched.step / rs5025xk-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rs5025xk.step / rs5025xk.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
rs5025xk.step 122 KB You want the bare part, or you mark your own boards.
rs5025xk-etched.step 2.0 MB You want the part with RS5025XK already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 488 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: Jiangsu RUNIC Tech datasheet (17 pp, sha256 3dc7f62e26d9c72a, retrieved 2026-08-17, tier: lcsc)
  • 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).
