AIC1117A-25GYTR from AIC Analog Integrations, in a SOT-223. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Power ground (device common). On the fixed-voltage AIC1117A-25 version, pin 1 is GND (this pin is the ADJ pin on the adjustable variant). |
| 2 | VOUT | power_out | Regulated 2.5V output (2.47V min, 2.50V typ, 2.53V max at VIN=5V). Delivers up to 1A. Also connected to the SOT-223 thermal tab. Requires a minimum 10µF (aluminum electrolytic recommended) capacitor to GND for stability. |
| 3 | VIN | power_in | Unregulated positive supply input. Must be at least VOUT + 1.3V (typical dropout at 1A). Absolute maximum VIN-to-GND is 7V. A 10µF input capacitor is recommended if the device is far from the bulk filter capacitors. |
