BD50FC0FP-E2

ROHM · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

BD50FC0FP-E2 from ROHM, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Vcc power_in Power supply input. Operating input voltage 4.0V to 26.5V (for Vo<3.0V) or Vo+1.0V to 26.5V (for Vo>=3.0V); withstand rating 35V. Decouple with an input capacitor Cin close to the pin.
2 N.C. unconnected No internal connection. Leave OPEN (per datasheet Note 1, this pin is not connected inside the IC).
3 Vo power_out Regulated 5.0V output pin, 1A maximum output current, ±1% accuracy at Ta=25°C. Requires a ceramic output capacitor Cout for stability.
FIN GND power_in Ground / thermal tab (FIN). Connects the package heat-slug to the PCB ground plane; also serves as the electrical GND reference for the regulator.

CAD (KiCad official)

  • Symbol: BD50FC0FP-E2
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: bd50fc0fp-e2-etched.step / bd50fc0fp-e2-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bd50fc0fp-e2.step / bd50fc0fp-e2.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: ROHM datasheet (41 pp, sha256 16de41a5714aae28, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
