UZ1086L-33-TN3-R from UTC(Unisonic Tech), in a TO-252-2(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 | Ground pin for the fixed-voltage regulator; the ordering note defines G as GND for fixed regulators, and the MPN's -33 suffix denotes the 3.3V fixed version. |
| 2 | VOUT | power_out | Regulated output pin that delivers up to 1.5A output current, with 3.3V fixed output for this part. |
| 3 | VIN | power_in | Input supply pin; the absolute maximum input voltage is 7.5V and the electrical characteristics for the 3.3V version specify VIN up to 7V. |
