LM337IMPX-TP from TECH PUBLIC, in a SOT-223-3. 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 | input | Adjust pin; sets the output voltage (adjustable between -1.2V and -37V), with a reference voltage of -1.25V typical to the output. |
| 2 | VIN | power_in | Input of supply voltage; input-output voltage differential is limited to 40V maximum, and the tab is also marked VIN. |
| 3 | VOUT | power_out | Output of the regulator, adjustable between -1.2V and -37V with output current up to 1.5A. |
