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 +5 V output. Delivers up to 100 mA of load current with ±4% tolerance (AB grade). A 0.1 µF ceramic capacitor to GND is recommended for stability and transient response. |+| 2 | GND | power_in | Ground / common return for input and output. Carries the small quiescent current (typ. a few mA) plus any output return current. |+| 3 | VIN | power_in | Unregulated DC input. Absolute maximum 30 V for the 5 V variant; must be at least VOUT + 1.7 V (typ. dropout) for regulation. A 0.33 µF ceramic input capacitor to GND is recommended when the regulator is far from the raw supply filter. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `L78L05ABUTRUTR`+- `L78L05ABUTRZ`+- `L78L05ABUTRAZ`+- `L78L05ABUTRCZ`+- `L78L05ABUTRD`+- `L78L05ABUTRD13TR`++## CAD (KiCad official)++- Symbol: `L78L05ABUTR`+- 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](https://www.st.com/resource/en/datasheet/l78l05abutr.pdf) (46 pp, sha256 `aebc91bfc9b4bb67`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
