78L33

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

78L33 from Shikues, 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 +3.3 V output. Delivers up to 150 mA. Recommended output bypass capacitor Co = 0.1 µF; not required for stability but improves transient response.
2 GND power_in Common ground reference. A common ground is required between the input and output voltages.
3 VIN power_in Unregulated positive supply input. Absolute max VIN = 30 V; must remain typically 2.0 V above VOUT (dropout ~2 V at IO=100 mA). Recommended input bypass capacitor Cin = 0.33 µF.

CAD (KiCad official)

  • Symbol: 78L33
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: 78l33-etched.step / 78l33-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 78l33.step / 78l33.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
78l33.step 57 KB You want the bare part, or you mark your own boards.
78l33-etched.step 1.0 MB You want the part with 78L33 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 268 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: Shikues datasheet (7 pp, sha256 2f2bf1f5a553c543, retrieved 2026-08-17, tier: lcsc)
  • 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).
