LM317L from HTC Korea TAEJIN Tech, in a TO-92-3. 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 | ADJ | passive | Adjustment terminal that sets the output voltage; the datasheet gives an adjustable pin current of 46 µA typical and 100 µA maximum. |
| 2 | VOUT | power_out | Regulated output, adjustable from 1.2 V to 37 V, supplying more than 100 mA of load current. |
| 3 | VIN | power_in | Unregulated input; the datasheet specifies regulation with an input-output differential of 3 V to 40 V. |
