MC78L15ACDR2G

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

MC78L15ACDR2G from onsemi, in a SOIC-8. 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 range 14.4 V to 15.6 V at TJ = 25 C, up to 100 mA. A 0.1 uF ceramic cap to GND improves transient response.
2 GND power_in Ground / common return. Pins 2, 3, 6, and 7 are electrically common to the die-attach flag in this modified SO-8 package to improve thermal dissipation; tie all four to the PCB ground pour.
3 GND power_in Ground / common return. Electrically common to pins 2, 6, 7 and the die-attach flag; used as a thermal path to the board.
4 NC unconnected No internal connection. May be left floating or tied to GND on the PCB.
5 NC unconnected No internal connection. May be left floating or tied to GND on the PCB.
6 GND power_in Ground / common return. Electrically common to pins 2, 3, 7 and the die-attach flag; used as a thermal path to the board.
7 GND power_in Ground / common return. Electrically common to pins 2, 3, 6 and the die-attach flag; used as a thermal path to the board.
8 VIN power_in Unregulated input supply. Recommended operating range 17.5 V to 30 V for the 15 V variant; absolute maximum 35 V (VI class 12 V-18 V rated to 35 V absolute max). A 0.33 uF cap to GND is required when the regulator is located far from the supply filter.

CAD (KiCad official)

  • Symbol: MC78L15ACDR2G
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: mc78l15acdr2g-etched.step / mc78l15acdr2g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc78l15acdr2g.step / mc78l15acdr2g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
mc78l15acdr2g.step 122 KB You want the bare part, or you mark your own boards.
mc78l15acdr2g-etched.step 2.5 MB You want the part with MC78L15ACDR2G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 611 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: onsemi datasheet (19 pp, sha256 6ff9a93de09c52e0, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
