UZ1085G-AD-TN3-R from UTC(Unisonic Tech), in a TO-252-2. 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 | ADJ | passive | Adjust pin for the adjustable (AD) version, which sets the output voltage against the 1.25V reference (1.225V to 1.275V) and has an adjust pin current of 35µA typ and 120µA max. |
| 2 | VOUT | power_out | Regulated output delivering up to 3A, with a minimum load current of 10mA max and a 22µF output capacitor (COUT) used in the datasheet test conditions. |
| 3 | VIN | power_in | Input supply pin with an absolute maximum of 18V and a dropout voltage of 1.30V typ and 1.40V max at 3A. |
