Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | Ground reference pin for the fixed-voltage variant (UZ1085-33). Internal feedback divider references this pin to set the 3.3V output. On the TO-252 package this is pin 1 and is electrically distinct from the tab. |+| 2 | VOUT | power_out | Regulated 3.3V output (min 3.234V, typ 3.3V, max 3.366V) capable of sourcing up to 3A. Requires a 22µF output capacitor for stability. Pin 2 is also electrically connected to the exposed tab of the TO-252 package. |+| 3 | VIN | power_in | Unregulated input supply. For the 3.3V fixed variant the recommended input range is 4.8V ≤ VIN ≤ 10.3V; absolute maximum input voltage is 18V. A 22µF input capacitor is recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UTC Unisonic Tech |+| Package | TO-252-2(DPAK) |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `UZ1085L-33-TN3-RTN3-R`+- `UZ1085L-33-TN3-RTA3-T`+- `UZ1085L-33-TN3-RTF3-T`+- `UZ1085L-33-TN3-RTQ2-T`+- `UZ1085L-33-TN3-RTQ2-R`+- `UZ1085L-33-TN3-RTQ3-T`+- `UZ1085L-33-TN3-RTQ3-R`++## CAD (KiCad official)++- Symbol: `UZ1085L-33-TN3-R`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252-2(DPAK) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UTC Unisonic Tech datasheet](docs/uz1085l-33-tn3-r-datasheet.pdf) (7 pp, sha256 `a0899cf558b465e2`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
