AIC1734-18GXATR

AIC Analog Integrations · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

AIC1734-18GXATR from AIC Analog Integrations, in a SOT-89-3. 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 power_in Power ground return for the regulator. Common return for both input and output.
2 VIN power_in Unregulated power supply input. Absolute maximum 12V (min -0.3V); typical operating range 4.0V-12V (5.5V-12V for the 5.0V/5.2V versions). Bypass with a 1µF input capacitor.
3 VOUT power_out Regulated output pin. For AIC1734-18: 1.8V ±2% at up to 300mA. Requires a 1µF output capacitor for loop stability (aluminum electrolytic recommended; ceramic not suggested per Note 1).

CAD (KiCad official)

  • Symbol: AIC1734-18GXATR
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: aic1734-18gxatr-etched.step / aic1734-18gxatr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); aic1734-18gxatr.step / aic1734-18gxatr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
aic1734-18gxatr.step 57 KB You want the bare part, or you mark your own boards.
aic1734-18gxatr-etched.step 1.8 MB You want the part with AIC1734-18GXATR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 472 faces against 42 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.
