AIC1084-18GMTR from AIC Analog Integrations, in a TO-263-2. 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 | ADJ (GND) | power_in | ADJ pin provides VREF=1.25V (typ.) for the adjustable output, with VREF=VOUT-VADJ and IADJ=55µA (typ.); the GND pin is power ground. |
| 2 | VOUT (TAB) | power_out | Adjustable output voltage pin, also connected to the metal tab; dropout is guaranteed at a maximum of 1.5V at 5A output current. |
| 3 | VIN | power_in | Power input pin; the absolute maximum rating for VIN to ADJ/GND is 7V. |
