LM317MKVURG3 from Texas Instruments, in a TO-252. 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 | ADJUST | input | Feedback voltage input pin; connect external resistor divider network to set output voltage from 1.25V to 37V. |
| 2 | OUTPUT | power_out | Regulated output voltage pin (1.25V to 37V maximum); place 0.1µF output capacitor as close as possible to this pin and common reference. |
| 3 | INPUT | power_in | Input power supply pin; accepts voltage 2.5V to 37V above the output voltage (VI − VO); place 0.1µF input capacitor close to pin. |
