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

NCV1117DT12RKG from onsemi, in a DPAK. 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
1 Adjust/Ground power_in Pin 1 is the Adjust/Ground terminal; on the fixed 12 V device it serves as the ground reference, and the datasheet gives no separate electrical limit for it.
2 Output power_out Regulated 12 V output, specified at 11.88 V to 12.12 V (Vin = 14 V, Iout = 10 mA, 25 °C) and 11.76 V to 12.24 V over Vin = 13.5 V to 20 V and Iout = 0 mA to 800 mA; output current must not exceed 1.0 A when Vin is greater than 12 V. The heatsink tab is connected to this pin.
3 Input power_in Unregulated input supply, with a maximum input voltage of 20 V; the 12 V fixed device is specified for Vin = 13.5 V to 20 V at Iout = 0 mA to 800 mA.

CAD (KiCad official)

  • Symbol: NCV1117DT12RKG
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK (KiCad packages3D, STEP)
  • 3D model files: ncv1117dt12rkg-etched.step / ncv1117dt12rkg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ncv1117dt12rkg.step / ncv1117dt12rkg.glb are the bare package body.
