PJ78M15TE from PJSEMI, in a TO-252. 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 | VIN | power_in | Unregulated input supply to the regulator; absolute maximum input voltage is 35 V, and the PJ78M15TE is specified for VI of 17.5 V to 30 V at 350 mA output. |
| 2 | GND | power_in | Common ground reference for the regulator, to which the input and output capacitors are returned. |
| 3 | VOUT | power_out | Regulated 15 V output (14.25 V to 15.75 V over IO = 5 mA to 350 mA), rated for output current up to 500 mA. |
