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. |
