LDK320ADU30R

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

LDK320ADU30R from STMicroelectronics, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Common ground terminal establishing 0 V reference potential for all circuit voltage measurements.
2 IN power_in Input voltage supply terminal; operates from 2.5 V to 18 V DC; bypass with 1 μF capacitor for stability.
3 OUT power_out Regulated output voltage nominally 3.0 V ±0.5% at 25°C, supplying up to 200 mA with internal current limiting and thermal shutdown at 160°C.

CAD (KiCad official)

  • Symbol: LDK320ADU30R
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: ldk320adu30r-etched.step / ldk320adu30r-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ldk320adu30r.step / ldk320adu30r.glb are the bare package body.
