L78L06ABUTR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

L78L06ABUTR from STMicroelectronics, in a SOT-89-3. 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 VOUT power_out Regulated +6 V output (typ 6 V, ±4% for AB grade). Sources up to 100 mA. A 0.1 uF ceramic capacitor to GND is recommended close to the pin for stability and transient response.
2 GND power_in Common ground reference for both input and output. In the SOT-89 package the center lead is fused to the die-attach tab, providing the primary thermal path.
3 VIN power_in Unregulated DC input. Recommended operating range is roughly VOUT + 2 V (dropout) up to 20 V; absolute maximum is 30 V for the 6 V variant. A 0.33 uF input capacitor to GND is recommended to suppress source impedance effects.

Two STEP files. Same geometry, different body top:

File Size Use it when
l78l06abutr.step 57 KB You want the bare part, or you mark your own boards.
l78l06abutr-etched.step 1.5 MB You want the part with L78L06ABUTR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 406 faces against 42 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 (45 pp, sha256 43922ae159face7e, 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).
