AiP1117-1.8GH223.TR

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).
