KIA7912F-RTF from KEC Semicon, in a DPAK. 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 for the regulator; the datasheet lists it as pin 1 of the DPAK package. |
| 2 | INPUT | power_in | Unregulated negative input voltage; the absolute maximum input voltage for KIA7905F to KIA7915F is -35 V, and the datasheet recommends a 2.2 µF input capacitor. |
| 3 | OUTPUT | power_out | Regulated -12 V (typical) output for the KIA7912F, rated for output current in excess of 1.0 A with internal short-circuit current limiting and thermal overload protection. |
