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

78L06-150 from UMW, 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. Typical Vo = 6.0 V (5.94-6.06 V at Tj=25 °C). Deliver up to 150 mA; place a 0.1 µF ceramic to GND close to the pin for stability.
2 GND power_in Ground / common return for the regulator. Serves as the reference for both Vin and Vout; also the thermal path of the SOT-89 package (pin 2 = tab).
3 INPUT power_in Unregulated positive supply input. For Vo=6 V variant the input must be ≥ ~8 V (Vin ≥ Vout + 1.7 V dropout) and ≤ 35 V absolute maximum. Decouple with a 0.33 µF ceramic to GND close to the pin.

CAD (KiCad official)

  • Symbol: 78L06-150
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: 78l06-150-etched.step / 78l06-150-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 78l06-150.step / 78l06-150.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
78l06-150.step 57 KB You want the bare part, or you mark your own boards.
78l06-150-etched.step 1.4 MB You want the part with 78L06-150 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 358 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: UMW datasheet (17 pp, sha256 fe2f4e8f0d975d52, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
