TL317CDR from Texas Instruments, 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 | INPUT | power_in | Positive input supply voltage; requires 2.5V to 35V differential above output for regulation. |
| 2 | OUTPUT | output | Output voltage terminal (1.25V to 32V); internally connected to pins 3, 6, and 7. |
| 3 | OUTPUT | output | Output voltage terminal (1.25V to 32V); internally connected to pins 2, 6, and 7. |
| 4 | ADJUSTMENT | input | Reference voltage input terminal; biased with 50µA to 100µA adjustment current for feedback divider programming. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUTPUT | output | Output voltage terminal (1.25V to 32V); internally connected to pins 2, 3, and 7. |
| 7 | OUTPUT | output | Output voltage terminal (1.25V to 32V); internally connected to pins 2, 3, and 6. |
| 8 | NC | unconnected | No internal connection. |
