NCP785AH50T1G from onsemi, in a SOT-89-3. 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 | Supply voltage input; the datasheet specifies a DC operating input range of 25 V to 450 V for VOUT = 3.3 V and 50 V to 450 V for VOUT = 5.0 V, and calls for a 2.2 µF capacitor from VIN to GND. |
| 2 | GND | power_in | Ground connection; the tab is also internally GND, so pin 2 and the tab share this potential. |
| 3 | VOUT | power_out | Regulator output; connect a 22 µF or larger MLCC capacitor from VOUT to GND, with fixed output options of 3.3 V, 5.0 V, 12 V and 15 V. |
