L5972D from STMicroelectronics, in a SOP-8. 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 | OUT | output | Regulator output with adjustable voltage from 1.235V to 35V. |
| 2 | GND | power_in | Ground. |
| 3 | GND | power_in | Ground. |
| 4 | COMP | output | Error amplifier output for frequency compensation with output voltage range 0.4V to 3.5V and maximum analog rating of 4V. |
| 5 | FB | input | Feedback input for output voltage selection with maximum rating of 4V; direct connection results in 1.235V output; external resistive divider required for higher output voltages. |
| 6 | GND | power_in | Ground. |
| 7 | GND | power_in | Ground. |
| 8 | VCC | power_in | Unregulated DC input voltage with operating range 4.4V to 36V and absolute maximum rating of 40V. |
