LM317HVT from Texas Instruments, in a TO-220. 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 | ADJ | input | Adjust pin; the regulator maintains a constant 1.25V reference voltage between VOUT and ADJ to set the output voltage through external resistor network. |
| 2 | VOUT | power_out | Output voltage pin; supplies regulated output voltage from 1.25V to 57V with maximum 1.5A output current capability. |
| 3 | VIN | power_in | Input supply voltage pin; accepts input voltage with maximum input-to-output differential of 60V. |
