LM2940IT-5.0G 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 | IN | power_in | Input supply voltage pin; recommended operating input is 6-26 V (absolute maximum 45 V). |
| 2 | GND | power_in | Ground pin; the TO-220-3 tab is also connected to GND. |
| 3 | OUT | power_out | LDO regulator output pin, delivering up to 1 A (5.00 V typical for the -5.0 version). |
