LM7905D2TRG from HANSCHIP semiconductor, in a TO-263-2. 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 | Ground pin, the reference for the -5 V regulator (LM7905: output -4.82 V to -5.18 V). |
| 2 | INPUT | power_in | Negative unregulated input, shown as the shortened middle lead that is also marked as the tab INPUT; absolute maximum -35 V at TJ=25°C. |
| 3 | OUTPUT | power_out | Regulated negative output of -5 V (-4.82 V to -5.18 V) with output current in excess of 1.0 A. |
