L78M05CV from STMicroelectronics, 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 | INPUT | power_in | Unregulated DC input supply pin; maximum DC input voltage is 35 V for VO = 5 to 18 V versions (40 V for 20/24 V versions) per the absolute maximum ratings, with a typical dropout voltage of 2 V above the regulated output. |
| 2 | GROUND | power_in | Common/ground reference pin for the regulator; also the reference node from which the fixed output voltage is measured (note the device has no external sense lead). |
| 3 | OUTPUT | output | Regulated positive DC output pin, delivering an output current up to 0.5 A at the fixed nominal voltage (5 V for the L78M05CV, 4.75-5.25 V over the rated line/load conditions), protected by internal current limiting, thermal shutdown and safe-area (SOA) protection. |
