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 V to 5.2 V at Tj=25 C). Sources up to 100 mA. A 0.1 uF output capacitor is recommended to improve transient response. |+| 2 | GND | power_in | Ground / common reference. Pins 2, 3, 6, and 7 are all electrically common to the internal die attach flag for improved thermal dissipation and must be tied to ground. |+| 3 | GND | power_in | Ground / common reference. Electrically common with pins 2, 6, 7 and the die attach flag; tie to ground plane to lower thermal resistance. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to GND at the user's discretion. |+| 5 | NC | unconnected | No internal connection. Leave floating or tie to GND at the user's discretion. |+| 6 | GND | power_in | Ground / common reference. Electrically common with pins 2, 3, 7 and the die attach flag; tie to ground plane for thermal dissipation. |+| 7 | GND | power_in | Ground / common reference. Electrically common with pins 2, 3, 6 and the die attach flag; tie to ground plane for thermal dissipation. |+| 8 | VIN | power_in | Unregulated positive input voltage. For the 5 V variant, absolute maximum is 30 V; typical operating range is 7.0 V to 20 V. Must remain ~2 V above VOUT even at the ripple valley. A 0.33 uF input capacitor is required if the regulator is located away from the power supply filter. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `MC78L05ABDR2GDR2G`+- `MC78L05ABDR2GDG`+- `MC78L05ABDR2GP`+- `MC78L05ABDR2GRP`+- `MC78L05ABDR2GRPG`+- `MC78L05ABDR2GZP`+- `MC78L05ABDR2GZPG`+- `MC78L05ABDR2GAPG`+- `MC78L05ABDR2GABPG`+- `MC78L05ABDR2GACPG`++## CAD (KiCad official)++- Symbol: `MC78L05ABDR2G`+- 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/mc78l05ab-d.pdf) (14 pp, sha256 `5e07299724d54f75`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
