LM1085T-5.0 from HGSEMI, 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 | ADJ/GND | passive | Adjust pin on the ADJ version and ground reference pin on the fixed 3.3V/5.0V versions, to be kept close to the load ground to reduce line-resistance drops. |
| 2 | VOUT | power_out | Regulated output (5V, 4.9V to 5.1V for LM1085-5.0) with up to 3A load current, also connected to the tab, with 3.2A minimum current limit. |
| 3 | VIN | power_in | Input supply pin with absolute maximum of 15V and recommended 10V, requiring about 1.5V dropout at 3A. |
