L78M06CDT-TR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)

L78M06CDT-TR from STMicroelectronics, in a TO-252-2(DPAK). 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 voltage. Absolute maximum 35 V (for Vo = 5 to 18 V versions). Recommended input bypass capacitor Ci = 0.33 uF. Dropout voltage is typically 2 V, so Vi must exceed Vo + 2 V for regulation.
2 GND power_in Common ground reference for the regulator. Electrically connected to the DPAK exposed tab (heat-slug), which is the primary thermal path (Rth j-c = 8 degC/W). Solder the tab to a copper pour for heat dissipation.
3 OUTPUT power_out Regulated +6 V output. Delivers up to 500 mA continuous with adequate heatsinking. Recommended output bypass capacitor Co = 0.1 uF placed close to the pin to improve transient response. Internally current-limited (Isc typ 300 mA at Vi = 35 V) and thermally protected.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
l78m06cdt-tr.step 119 KB You want the bare part, or you mark your own boards.
l78m06cdt-tr-etched.step 1.7 MB You want the part with L78M06CDT-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 460 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.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (47 pp, sha256 7cee4c5f6a43332c, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
