**Wuxi I-core Elec** · Linear Voltage Regulators (LDO) · SOT-223

AiP1117-1.8GH223.TR from Wuxi I-core Elec, in a SOT-223. 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 pin for the fixed-output version (AiP1117-1.8); the same pin serves as ADJ on the adjustable AiP1117-ADJ. |
| 2 | VOUT | power_out | Regulated 1.8V output (typ. 1.8V, 1.764-1.836V) delivering up to 1A; the package tab/substrate is also connected to VOUT. |
| 3 | VIN | power_in | Input supply pin, recommended 2.75V to 18V (absolute maximum 20V). |
