AIC1117A-33GYTR 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 return for the fixed-voltage device. On the adjustable AIC1117A this pin is the ADJ feedback node (VREF = 1.25V typ, IADJ = 55μA typ); on fixed 3.3V AIC1117A-33 it is tied internally as the regulator ground reference.
2	VOUT	power_out	Regulated 3.3V output (3.26V min / 3.30V typ / 3.33V max at VIN=5V). Rated for up to 1A load current; internal current limit is guaranteed at ≥1A. Requires a ≥10μF output capacitor for stability; aluminum electrolytic or tantalum recommended.
3	VIN	power_in	Unregulated power input. Absolute maximum VIN-to-GND is 7V. Recommended operating range is 2.65V ≤ VIN ≤ 7V; dropout is 1.3V typ / 1.5V max at 1A, so VIN must be ≥ VOUT + dropout. A 10μF input capacitor (C1) is recommended if the device is far from the bulk filter capacitors.
