LM317LCPWR from Texas Instruments, in a TSSOP-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 | INPUT | power_in | Input power supply voltage, requires minimum 2.5 V above output voltage for regulation operation |
| 2 | NC | unconnected | No internal connection; recommend grounding for improved thermal performance but not required |
| 3 | NC | unconnected | No internal connection; recommend grounding for improved thermal performance but not required |
| 4 | ADJUSTMENT | input | Output feedback voltage input with 1.256 V nominal reference voltage for output voltage regulation |
| 5 | NC | unconnected | No internal connection; recommend grounding for improved thermal performance but not required |
| 6 | OUTPUT | power_out | Regulated output voltage capable of supplying 2.5 to 100 mA continuous output current |
| 7 | NC | unconnected | No internal connection; recommend grounding for improved thermal performance but not required |
| 8 | NC | unconnected | No internal connection; recommend grounding for improved thermal performance but not required |
