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 +5.0 V output (4.8-5.2 V typ at 25 degC). Sources up to 100 mA. Recommended 0.1 uF ceramic to GND for transient response (not required for stability). |+| 2 | GND | power_in | Ground reference. Electrically common to die attach flag along with pins 3, 6, 7 for improved thermal dissipation; connect all four to the ground copper pour. |+| 3 | GND | power_in | Ground reference. Electrically common to die attach flag along with pins 2, 6, 7; connect to ground copper for thermal dissipation. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to ground. |+| 5 | NC | unconnected | No internal connection. Leave floating or tie to ground. |+| 6 | GND | power_in | Ground reference. Electrically common to die attach flag along with pins 2, 3, 7; connect to ground copper for thermal dissipation. |+| 7 | GND | power_in | Ground reference. Electrically common to die attach flag along with pins 2, 3, 6; connect to ground copper for thermal dissipation. |+| 8 | VIN | power_in | Unregulated positive input. Absolute max 30 Vdc for the 5 V version; typical operating range 7 V to 20 V. Recommended 0.33 uF ceramic to GND if regulator is remote from the bulk supply filter. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `MC78L05ACDR2GDR2G`+- `MC78L05ACDR2GDG`+- `MC78L05ACDR2GPG`+- `MC78L05ACDR2GRPG`+- `MC78L05ACDR2GRAG`+- `MC78L05ACDR2GZG`++## CAD (KiCad official)++- Symbol: `MC78L05ACDR2G`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/mc78l05ac-d.pdf) (14 pp, sha256 `5e07299724d54f75`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
