RT9058-33GV

Richtek Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

RT9058-33GV from Richtek Tech, in a SOT-23. 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 VCC power_in Supply voltage input. Operating range 3.5V to 36V (absolute max 40V). Bypass to GND with a 1 uF or larger capacitor placed close to the pin.
2 VOUT power_out Regulated output of the LDO. Fixed 3.3V, +/-2% accuracy, up to 100mA. Requires an output capacitor with effective capacitance >= 1 uF and ESR >= 1 mOhm for stability.
3 GND power_in Device ground reference. Return path for input bypass and output capacitors.

CAD (KiCad official)

  • Symbol: RT9058-33GV
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: rt9058-33gv-etched.step / rt9058-33gv-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rt9058-33gv.step / rt9058-33gv.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
rt9058-33gv.step 59 KB You want the bare part, or you mark your own boards.
rt9058-33gv-etched.step 2.3 MB You want the part with RT9058-33GV already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 543 faces against 69 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: Richtek Tech datasheet (9 pp, sha256 354cc97a6b06f099, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
