MC7915CD2TR4G

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-2

MC7915CD2TR4G from onsemi, in a TO-263-2. 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 GND power_in Ground / common reference. Return current for the regulator; forms the reference node against which the -15 V output is developed.
2 VI power_in Negative input voltage. Must be at least ~2 V more negative than VO under the ripple minimum (dropout ~1.3 V typ). Absolute maximum -35 Vdc (part-family limit for -5 V ≤ VO ≥ -18 V variants). The exposed heatsink tab (terminal 4 of the D2PAK case outline) is electrically connected to this pin.
3 VO power_out Regulated negative output, -15 V nominal (MC7915C: -14.4 V to -15.6 V at TJ = 25 °C). Sources up to 1.0 A with adequate heatsinking. A 1.0 µF output capacitor is recommended for stability and transient response.

Two STEP files. Same geometry, different body top:

File Size Use it when
mc7915cd2tr4g.step 108 KB You want the bare part, or you mark your own boards.
mc7915cd2tr4g-etched.step 2.0 MB You want the part with MC7915CD2TR4G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 521 faces against 79 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 (16 pp, sha256 01e22db47f1a6088, 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).
