NCP163ASN500T1G

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

NCP163ASN500T1G from onsemi, in a SOT-23-5. 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 IN power_in Input voltage supply pin. Operating range 2.2 V to 5.5 V; bypass with 1 µF ceramic capacitor to GND. Absolute max -0.3 V to 6 V.
2 GND power_in Common ground connection for the regulator.
3 EN input Chip enable input. V_EN < 0.4 V disables the regulator; V_EN > 1.2 V enables the LDO. Internal ~280 kΩ pull-down (I_EN ≈ 0.2 µA typ at 4.8 V). Absolute max -0.3 V to 6 V.
4 NC unconnected Not connected internally. May be tied to the ground plane for improved PCB layout / thermal spreading.
5 OUT power_out Regulated 5.0 V output, up to 250 mA. Must be bypassed with a 1 µF ceramic capacitor. Version A includes an active discharge path (~280 Ω) when EN is low.

CAD (KiCad official)

  • Symbol: NCP163ASN500T1G
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ncp163asn500t1g-etched.step / ncp163asn500t1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ncp163asn500t1g.step / ncp163asn500t1g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ncp163asn500t1g.step 85 KB You want the bare part, or you mark your own boards.
ncp163asn500t1g-etched.step 2.7 MB You want the part with NCP163ASN500T1G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 659 faces against 102 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 (23 pp, sha256 024c06f95e392f4d, 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).
