LM7906T from HGSEMI, in a TO-220-3. 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 | GND | power_in | Common ground reference pin of the LM7906 negative regulator, listed as GND in the TO220-3 pin configuration. |
| 2 | Input | power_in | Negative unregulated input, with absolute maximum input voltage of -35 V at TJ=25°C and an LM7906 operating input range of -8.0 V to -21 V. |
| 3 | Output | power_out | Regulated negative output with output voltage between -5.77 V and -6.23 V over 5.0 mA to 1.0 A load, rated for output current in excess of 1.0 A. |
