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. |
