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 | VOUT | power_out | Regulated +10 V output. Nominal 10 V (min 9.2 V, max 10.8 V at TJ=25 °C); delivers up to 100 mA. A 0.1 µF ceramic capacitor to GND is recommended for stability and transient response. |+| 2 | GND | power_in | Common ground reference for input and output. On the SOT-89 package the GND pin is also electrically connected to the die-attach tab on the top of the package for heat dissipation. |+| 3 | VIN | power_in | Unregulated DC input. For the 10 V option VI must exceed VOUT by at least the dropout (~1.7 V typ) and stay within the 30 V absolute-max input rating (VO 3.3-9 V range spec). A 0.33 µF ceramic input capacitor to GND is recommended, particularly when the regulator is located far from the power-supply filter. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `L78L10ACUTRUTR`+- `L78L10ACUTRZ`+- `L78L10ACUTRD`++## CAD (KiCad official)++- Symbol: `L78L10ACUTR`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](docs/l78l10acutr-datasheet.pdf) (40 pp, sha256 `8b73c521b7f1b36e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
