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 | VIN | power_in | Unregulated input voltage pin. Accepts up to 35V absolute max; typical operating input for the 5V version is 7V with dropout of ~0.6V. Bypass with CI > 0.33uF electrolytic near the pin if far from the supply filter. |+| 3 | VOUT | power_out | Regulated 5V (typ, +/-2.4%) output pin, rated for up to 1A load current. Requires CO > 47uF electrolytic to ground for stability and transient response. |+| 2 | GND | power_in | Ground reference. In TO-252 this is the tab/pin 2. Also serves as the thermal path to PCB copper. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UTC Unisonic Tech |+| Package | TO-252-2(DPAK) |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `78R05G-TN3-R`+- `78R05G-TN3-RL-TN3-R`+- `78R05G-TN3-RTN5-R`+- `78R05G-TN3-RL-TN5-R`+- `78R05G-TN5-R`+- `78R05G-TN3-RTB5-T`+- `78R05G-TN3-RL-TB5-T`+- `78R05G-TN3-RG-TB5-T`+- `78R05G-TN3-RTF4-T`+- `78R05G-TN3-RL-TF4-T`+- `78R05G-TN3-RG-TF4-T`++## CAD (KiCad official)++- Symbol: `78R05G-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/78r05g-tn3-r-datasheet.pdf) (9 pp, sha256 `6478f9c74b2eab0a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
