TPL820F33-89TR

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

TPL820F33-89TR from 3PEAK, 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 OUT power_out Regulated output voltage pin. Fixed 3.3 V nominal (±1% at TJ = 25°C), sourcing up to 180 mA. Requires a 2.2 µF to 22 µF low-ESR ceramic output capacitor for stability.
2 GND power_in Ground reference pin. Connect directly to the PCB ground plane for best thermal performance and noise immunity.
3 IN power_in Input voltage pin. Accepts 3.6 V to 42 V (absolute max 45 V). Requires a bypass capacitor to GND; typical application uses a ceramic input capacitor.

CAD (KiCad official)

  • Symbol: TPL820F33-89TR
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: tpl820f33-89tr-etched.step / tpl820f33-89tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpl820f33-89tr.step / tpl820f33-89tr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tpl820f33-89tr.step 57 KB You want the bare part, or you mark your own boards.
tpl820f33-89tr-etched.step 2.1 MB You want the part with TPL820F33-89TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 531 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.
