REF3225AIDBVR

Texas Instruments · Voltage Reference · SOT-23-6

REF3225AIDBVR from Texas Instruments, in a SOT-23-6. 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 GND_F power_in Ground force pin. Analog output; the ground connection of the device that carries the ground return current. Used in Kelvin (force/sense) configuration with GND_S to null out IR drops in ground routing.
2 GND_S input Ground sense pin. Analog input; connects at the load to sense the load-side ground potential, enabling force/sense (Kelvin) load regulation compensation.
3 ENABLE input Digital input that enables (V_H ≥ 1.5V, up to V_IN) or disables (V_L ≤ 0.7V) the reference. In shutdown, supply current drops to ~0.1µA (1µA max). May be tied to IN for input rise times ≤ 2ms.
4 IN power_in Positive supply voltage input. Analog input; operating range V_OUT + 0.05V (dropout) to 5.5V. Absolute maximum 7.5V. Quiescent current typ 100µA.
5 OUT_S input Output sense pin. Analog input; sense connection at the load used with OUT_F in a Kelvin/force-sense configuration to null out IR drops in the output trace and improve load regulation.
6 OUT_F output Output force pin. Analog output that sources the 2.5V reference voltage (REF3225). Delivers up to ±10mA and is stable with any capacitive load.

CAD (KiCad official)

  • Symbol: REF3225AIDBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: ref3225aidbvr-etched.step / ref3225aidbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ref3225aidbvr.step / ref3225aidbvr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ref3225aidbvr.step 97 KB You want the bare part, or you mark your own boards.
ref3225aidbvr-etched.step 2.3 MB You want the part with REF3225AIDBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 582 faces against 117 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.
