Foshan Blue Rocket Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

78D05 from Foshan Blue Rocket Elec, 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 IN power_in Unregulated input voltage. Operating input range approximately 7 V to 25 V; absolute maximum 35 V. A 0.33 uF input bypass capacitor is recommended close to the pin.
2 GND power_in Ground / common return for the regulator. Pin 2 is electrically tied to pin 4 (tab) as the device's GND connection.
3 OUT power_out Regulated +5.0 V output (4.75 V to 5.25 V over line/load). Sources up to 1.5 A with internal thermal and short-circuit protection. A 0.1 uF output capacitor is recommended for stability.
4 GND power_in TO-252 heat-sink tab, internally connected to GND (common with pin 2). Provides the primary thermal path to the PCB copper pour.

CAD (KiCad official)

  • Symbol: 78D05
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: 78d05-etched.step / 78d05-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 78d05.step / 78d05.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
78d05.step 119 KB You want the bare part, or you mark your own boards.
78d05-etched.step 1.2 MB You want the part with 78D05 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 318 faces against 83 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
