# AIC1117-18GYTR

**AIC(Analog Integrations)** · Linear Voltage Regulators (LDO) · SOT-223

AIC1117-18GYTR from AIC(Analog Integrations), 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 | Power ground for the fixed 1.8V version (the pin is ADJ on the adjustable version, which provides VREF=1.25V typ.). |
| 2 | VOUT | power_out | Regulated output voltage (1.8V for this version), up to 800mA, also connected to the tab, and requires at least 10µF output capacitance for stability. |
| 3 | VIN | power_in | Power input, with absolute maximum of 7V from VIN to GND. |
