LD1086V33-DG from STMicroelectronics, in a TO-220. 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 for this fixed 3.3 V output version (labeled ADJ/GND in the generic pin diagram, since LD1086V33-DG is a fixed-voltage part this pin is the device ground). |
| 2 | OUTPUT | power_out | Regulated 3.3 V output pin, internally connected to the metal tab; requires a minimum 10 µF output capacitor for stability and supplies up to 1.5 A. |
| 3 | INPUT | power_in | Unregulated DC input supply pin, accepting up to 30 V absolute maximum, with typical dropout of 1.3 V at 1.5 A load. |
