NCP110AFCT120T2G

onsemi · Linear Voltage Regulators (LDO) · WLCSP-4(0.64x0.64)

NCP110AFCT120T2G from onsemi, in a WLCSP-4(0.64x0.64). 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, operating range 1.1 V to 5.5 V.
A2 OUT power_out Regulated output voltage (1.20 V for this variant); should be bypassed with a small 1 µF ceramic capacitor.
B1 EN input Chip enable: VEN < 0.2 V disables the regulator, VEN > 0.7 V enables the LDO; has internal pull-down current of typ. 200 nA.
B2 GND power_in Common ground connection.

CAD (KiCad official)

  • Symbol: NCP110AFCT120T2G
  • Footprint: Package_CSP:WLCSP-4_0.64x0.64mm_Layout2x2_P0.35mm
  • 3D model: WLCSP-4(0.64x0.64), 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: ncp110afct120t2g-etched.step / ncp110afct120t2g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ncp110afct120t2g.step / ncp110afct120t2g.glb are the bare package body.
