AIC1734-27GXATR

AIC(Analog Integrations) · Linear Voltage Regulators (LDO) · SOT-89-3

AIC1734-27GXATR from AIC(Analog Integrations), in a SOT-89-3. 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 GND pin that provides the electrical ground connection and also conducts heat away from the package.
2 VIN power_in Power supply input pin; the datasheet's absolute maximum input supply voltage is -0.3 to 12V.
3 VOUT power_out Regulated output pin, which needs at least a 1uF aluminum electrolytic output capacitor for stability.
