LM1085IT-3.3G from HANSCHIP semiconductor, in a TO-220-3. 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 | Ground reference pin of the fixed 3.3V version (labelled ADJ/GND; it is the adjust pin on the ADJ version), with a typical ground pin current of 7mA and a maximum of 10mA. |
| 2 | VOUT | power_out | Regulated 3.3V output (±2% over 0 to 3A load), also connected to the metal tab, with current limit of 3A min and an output capacitor required for stability (22µF tantalum or 150µF aluminum). |
| 3 | VIN | power_in | Input voltage pin, absolute maximum 15V, with dropout of 1.5V max at 3A load. |
