LM317LBDR2G from onsemi, in a SOIC-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 | Vin | power_in | Input supply voltage for the regulator; maximum input-output voltage differential VI-VO = 40 Vdc |
| 2 | Vout | power_out | Regulated output voltage; output voltage range 1.2 V to 37 V |
| 3 | Vout | power_out | Regulated output voltage; output voltage range 1.2 V to 37 V |
| 4 | Adjust | output | Reference voltage terminal providing 1.25 V nominal above ground; external resistor divider connected to this pin sets the regulated output voltage |
| 5 | N.C. | unconnected | No connection |
| 6 | Vout | power_out | Regulated output voltage; output voltage range 1.2 V to 37 V |
| 7 | Vout | power_out | Regulated output voltage; output voltage range 1.2 V to 37 V |
| 8 | N.C. | unconnected | No connection |
