LP2950CDT-5.0RKG

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)

LP2950CDT-5.0RKG from onsemi, in a TO-252-2(DPAK). 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 Input power_in Unregulated input supply. Absolute max VCC = 30 Vdc (32 V peak transient <300 ms). A 1.0 µF bypass capacitor to ground is recommended if the input source is more than 4 inches of wire away from a battery or filter cap.
2 Ground power_in Device ground reference. The DPAK heatsink tab (mechanical terminal 4) is internally connected to this pin, so the mounting pad is at ground potential.
3 Output power_out Regulated 5.0 V output, capable of >100 mA. Requires a minimum 1.0 µF output capacitor for stability (aluminum, tantalum, or MLCC acceptable). Internal current limit typically 220 mA, with thermal shutdown protection.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lp2950cdt-5-0rkg.step 119 KB You want the bare part, or you mark your own boards.
lp2950cdt-5-0rkg-etched.step 2.3 MB You want the part with LP2950CDT-5.0RKG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 601 faces against 83 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 (22 pp, sha256 a61aad4d8579aefb, 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).
