CJ78L12-TA from Changjiang Electronics Tech (CJ), in a TO-92-2.54mm. 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 | OUT | power_out | Regulated 12V output (Vo 11.5V min to 12.5V max at 25°C), maximum output current 0.1A, with a 0.1µF bypass capacitor recommended close to the regulator. |
| 2 | GND | power_in | Ground reference pin, common to the input and output bypass capacitors. |
| 3 | IN | power_in | Unregulated input voltage, absolute maximum 35V, with a 0.33µF bypass capacitor recommended close to the regulator. |
