NCP163AFCS280T2G

onsemi · Linear Voltage Regulators (LDO) · WLCSP-4(0.6x0.6)

NCP163AFCS280T2G from onsemi, in a WLCSP-4(0.6x0.6). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
A1 IN power_in Input voltage supply pin; the operating input voltage range is 2.2 V to 5.5 V, with an absolute maximum of -0.3 V to 6 V.
A2 OUT power_out Regulated output voltage that should be bypassed with a small 1 µF ceramic capacitor placed close to the pin.
B1 EN input Chip enable: VEN below 0.4 V disables the regulator and VEN above 1.2 V enables the LDO.
B2 GND power_in Common ground connection.

CAD (KiCad official)

  • Symbol: NCP163AFCS280T2G
  • Footprint: Package_CSP:WLCSP-4_0.64x0.64mm_Layout2x2_P0.35mm
  • 3D model: WLCSP-4(0.6x0.6), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.35 mm nominal DSBGA height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: ncp163afcs280t2g-etched.step / ncp163afcs280t2g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ncp163afcs280t2g.step / ncp163afcs280t2g.glb are the bare package body.
