NCV4264-2ST50T3G

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-3

NCV4264-2ST50T3G from onsemi, in a SOT-223-3. 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 VIN power_in Unregulated input voltage. Operating range 4.5 V to 45 V; withstands transients from -42 V to +45 V. A 100 nF input capacitor is recommended.
2 GND power_in Ground; substrate connection. Tied internally to the TAB.
3 VOUT power_out Regulated output voltage; collector of the internal PNP pass transistor. Fixed 5.0 V ±2.0% at up to 100 mA. Requires a stability output capacitor of ≥10 µF (5.0 V version) with ESR within the specified stability window.
TAB GND power_in Ground; substrate and best thermal connection to the die. Solder to a copper pour for effective heat dissipation (θJA ~99 °C/W with 1 oz, 100 mm² copper).

CAD (KiCad official)

  • Symbol: NCV4264-2ST50T3G
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223-3 (KiCad packages3D, STEP)
  • 3D model files: ncv4264-2st50t3g-etched.step / ncv4264-2st50t3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ncv4264-2st50t3g.step / ncv4264-2st50t3g.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ncv4264-2st50t3g.step 64 KB You want the bare part, or you mark your own boards.
ncv4264-2st50t3g-etched.step 2.8 MB You want the part with NCV4264-2ST50T3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 672 faces against 75 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 (11 pp, sha256 46d2bf0aebb126d7, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
