AIC1747-28GU3TR

AIC(Analog Integrations) · Linear Voltage Regulators (LDO) · SOT-23

AIC1747-28GU3TR from AIC(Analog Integrations), in a SOT-23. 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 reference pin; it also channels heat away from the device, so a large ground pad or plane lowers junction temperature.
2 VOUT power_out Regulator output pin that sources up to 300 mA.
3 VIN power_in Power supply input operating from 2.0V to 6.0V (7V absolute maximum), to be bypassed with a 1µF capacitor to GND.
