XL317 from XINLUDA, in a SOP-8. 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 | VIN | power_in | Supply input pin; the input-to-output differential must stay within 2.5 V to 32 V under recommended conditions, and the absolute maximum input-output differential is 35 V. |
| 2 | VOUT | power_out | Voltage output pin, regulating over a 1.25 V to 32 V output range and supplying up to 100 mA. |
| 3 | VOUT | power_out | Voltage output pin, regulating over a 1.25 V to 32 V output range and supplying up to 100 mA. |
| 4 | ADJ | input | Output voltage adjustment pin, connected to a resistor divider to set VOUT; its current is typically 50 µA and at most 200 µA. |
| 5 | NC | unconnected | No connection. |
| 6 | VOUT | power_out | Voltage output pin, regulating over a 1.25 V to 32 V output range and supplying up to 100 mA. |
| 7 | VOUT | power_out | Voltage output pin, regulating over a 1.25 V to 32 V output range and supplying up to 100 mA. |
| 8 | NC | unconnected | No connection. |
