ICW1117A18PG

ICW · Linear Voltage Regulators (LDO) · SOT-89-3

ICW1117A18PG from ICW, 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 ADJ/GND power_in Ground reference pin (ADJ on the adjustable version) that should be connected to the low side of the load on fixed-output versions.
2 VOUT power_out Regulated output (1.8V ±2%, 1.764V to 1.836V, at 0 to 1A) that needs an output capacitor to GND with ESR not exceeding 0.5Ω.
3 VIN power_in Input supply pin (maximum input voltage 30V absolute maximum) that should have an input bypass capacitor such as 10µF tantalum.

CAD (KiCad official)

  • Symbol: ICW1117A18PG
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: icw1117a18pg-etched.step / icw1117a18pg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); icw1117a18pg.step / icw1117a18pg.glb are the bare package body.
