L4931CDT50-TR

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

L4931CDT50-TR 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 INPUT power_in Regulator input voltage pin; operating input voltage up to 20 V (absolute maximum 20 V), with a 0.1 µF input capacitor used in the test circuit.
2 GND power_in Ground pin, shown in the DPAK drawing as the middle stub connected to the tab (GND).
3 OUTPUT power_out Regulated 5 V output (L4931CDT50-TR) delivering up to 250 mA, requiring a 2.2 µF to 10 µF output capacitor with ESR of 0.1 to 10 Ω for stability.

  • Symbol: L4931CDT50-TR
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK (KiCad packages3D, STEP)
  • 3D model files: l4931cdt50-tr-etched.step / l4931cdt50-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l4931cdt50-tr.step / l4931cdt50-tr.glb are the bare package body.
