LP2950ACDT-5RKG

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

LP2950ACDT-5RKG 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). Operates with Vin as low as Vo + ~380 mV (dropout at 100 mA).
2 Ground power_in Device ground reference and return for quiescent bias current (~75 uA typ). Electrically connected internally to the DPAK heatsink tab (case terminal 4).
3 Output power_out Regulated 5.0 V output, up to 100 mA. Requires >=1.0 uF output capacitor for loop stability. Initial accuracy +/-0.5% ('A' suffix) at 25 C.
4 Tab passive DPAK heatsink tab. Internally bonded to Pin 2 (Ground). Solder to a ground copper pour to improve thermal dissipation (RthetaJA = 92 C/W, RthetaJC = 6.0 C/W for CASE 369C).

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lp2950acdt-5rkg.step 119 KB You want the bare part, or you mark your own boards.
lp2950acdt-5rkg-etched.step 2.2 MB You want the part with LP2950ACDT-5RKG already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 572 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 29409d2bf6c8b2de, 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).
