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

LM2931ADT50R from STMicroelectronics, 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 VOUT power_out Regulated output of the fixed 5 V version, which delivers up to 100 mA and is protected by internal current and thermal limiting.
2 GND power_in Ground reference pin of the regulator.
3 VIN power_in Unregulated input supply, with a maximum operating input voltage of 26 V, a 40 V maximum DC input rating, and a 60 V load dump transient rating (under 100 ms).

CAD (KiCad official)

  • Symbol: LM2931ADT50R
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK (KiCad packages3D, STEP)
  • 3D model files: lm2931adt50r-etched.step / lm2931adt50r-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm2931adt50r.step / lm2931adt50r.glb are the bare package body.
