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 | INPUT | power_in | Unregulated positive input supply. Absolute maximum V_I = 35V for the 5V variant. Bypass to GND with C_I = 0.33 µF close to the pin. |+| 2 | GND | power_in | Common ground reference for input and output. On TO-252/TO-252-3 the GND connection is also the thermal tab (die pad) and should be tied to a copper heatsink pour. |+| 3 | OUTPUT | power_out | Regulated +5V output. V_O typical 5.0V (4.8-5.2V at 25°C), up to 1A load current. Bypass to GND with C_O = 0.1 µF for stability. Internal short-circuit current limit ~800 mA (V_I = 35V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | TO-252-2 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `78D05LL`++## CAD (KiCad official)++- Symbol: `78D05L`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252-2 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/78d05l-datasheet.pdf) (15 pp, sha256 `0816f246cc64ec64`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
