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 +15 V output. Typical output 15 V (14.4 V min / 15.6 V max at TJ = 25 C), up to 100 mA. Recommend 0.1 uF ceramic to GND for transient response. |+| 2 | GND | power_in | Ground reference. SOIC-8 pins 2, 3, 6, and 7 are electrically common to the die-attach flag; tying all four together on the PCB copper improves thermal dissipation. |+| 3 | GND | power_in | Ground reference. Internally connected to die-attach flag along with pins 2, 6, 7. Tie all four ground pins to a copper ground pour for improved thermal performance. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to ground; not electrically connected to the die. |+| 5 | NC | unconnected | No internal connection. Leave floating or tie to ground; not electrically connected to the die. |+| 6 | GND | power_in | Ground reference. Internally common with pins 2, 3, 7 via the die-attach flag; connect all four to the ground pour for thermal dissipation. |+| 7 | GND | power_in | Ground reference. Internally common with pins 2, 3, 6 via the die-attach flag; connect all four to the ground pour for thermal dissipation. |+| 8 | VIN | power_in | Unregulated input supply. Must be at least ~1.7 V above VOUT (Vdrop ~ 1.7 V typ.); absolute maximum 30 V for the 15 V variant. Place a 0.33 uF input capacitor to GND if the regulator is located an appreciable distance from the power-supply filter. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `MC78L15ABDR2GDR2G`+- `MC78L15ABDR2GD`+- `MC78L15ABDR2GP`+- `MC78L15ABDR2GAP`+- `MC78L15ABDR2GABP`+- `MC78L15ABDR2GACP`+- `MC78L15ABDR2GG`++## CAD (KiCad official)++- Symbol: `MC78L15ABDR2G`+- 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/mc78l15ab-d.pdf) (20 pp, sha256 `385af0f745775d96`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
