SK7905U from Shikues, in a TO-252. 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 | GND | power_in | Ground / common return pin. Reference for both the negative input and the negative output voltage. On the TO-252 package this is also the tab-adjacent pin. |
| 2 | VIN | power_in | Negative input supply pin. Accepts the unregulated negative rail; absolute maximum -35V. Recommended operating range for -5V output is approximately -7V to -25V. A 2.2 uF input capacitor to GND is recommended. |
| 3 | VOUT | power_out | Regulated negative output pin. Provides -5.0V (typ) at up to 1.5A with a dropout voltage of ~2V at 1A. A 1 uF output capacitor to GND is recommended for stability. |
