ICW1117A25PG 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 | GND | power_in | Ground reference pin, labelled ADJ/GND on the package pinout (the ADJ function applies only to the adjustable version); for fixed-output versions the ground pin connects to the low side of the load. |
| 2 | VOUT | power_out | Regulated output pin (2.5V, 2.45V to 2.55V for this fixed version at 0 to 1A load), which needs a capacitor to GND with ESR not exceeding 0.5 ohm for stability. |
| 3 | VIN | power_in | Input supply pin with a maximum input voltage of 30V and a recommended 10uF tantalum bypass capacitor. |
