78M06

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

78M06 from UMW, 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 INPUT power_in Unregulated DC input. Absolute maximum 35 V (for 5-18 V output variants). Typical operating input for 78M06 is ~11 V; must be at least Vout + Vdropout (~2 V at 500 mA). Bypass with 0.33 µF ceramic close to the pin.
2 GND power_in Common ground reference for both input and output. On TO-252/SOT-223 this pin is electrically tied to the exposed tab, which also serves as the primary thermal path (θJC = 12.5 °C/W for TO-252, 15 °C/W for SOT-223).
3 OUTPUT power_out Regulated +6 V output (5.76 V-6.24 V typ at 25 °C). Up to 1 A continuous, 1.3 A peak. Internally current-limited (short-circuit current 800 mA typ). Bypass with 0.1 µF ceramic close to the pin for stability.

CAD (KiCad official)

  • Symbol: 78M06
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: 78m06-etched.step / 78m06-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 78m06.step / 78m06.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
78m06.step 119 KB You want the bare part, or you mark your own boards.
78m06-etched.step 1.3 MB You want the part with 78M06 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 324 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.
