LM1086T-3.3 from HGSEMI LM1086T 3 3, in a TO-220. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference for the regulator. On the fixed-voltage LM1086-3.3 version, this pin is the device ground return (labeled GND/ADJ in the datasheet - the ADJ function applies only to the adjustable version). |
| 2 | VOUT | power_out | Regulated 3.3V output (±2% initial accuracy, ±3.3% over line/load). Requires a minimum ~10µF output capacitor (22µF tantalum recommended) for stability. Delivers up to 1.5A continuous. |
| 3 | VIN | power_in | Unregulated input supply. Recommended operating range up to 15V (absolute max 20V). Must exceed VOUT by at least the 1.2V dropout at full 1.5A load. A ~10µF input capacitor is recommended. |
