L7905-1.5A from TDSEMIC, in a TO-220-3L. 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 for the regulator; the datasheet gives no separate voltage or current limit for this pin. |
| 2 | IN | power_in | Negative unregulated input voltage, with an absolute maximum of -35 V, and the datasheet's electrical characteristics are specified at Vi = -10 V with Ci = 2.2 μF. |
| 3 | OUT | power_out | Regulated negative output of nominally -5 V (-4.8 V to -5.2 V at 25 ℃), rated for output current up to 1.2 A and used with Co = 1 μF. |
