TPRT9161-33GV

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L

TPRT9161-33GV from TECH PUBLIC, in a SOT-23-3L. 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 GND power_in Ground / reference terminal. All internal reference and control circuitry is referenced to this pin.
2 VOUT power_out Regulated output terminal. Fixed 3.3V (typ) at up to 300mA. Requires a ceramic output capacitor (1µF-10µF, X5R/X7R recommended). Absolute max: GND-0.3V to +7V.
3 VIN power_in Unregulated supply input. Operates up to 18V (absolute max -0.3V to +20V). Requires a ceramic input capacitor (1µF-10µF). For VIN > 12V, an electrolytic/tantalum cap is recommended to absorb hot-plug surges.

Same part, different packaging or reel option.

  • TPRT9161-33GV

CAD (KiCad official)

  • Symbol: TPRT9161-33GV
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: tprt9161-33gv-etched.step / tprt9161-33gv-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tprt9161-33gv.step / tprt9161-33gv.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tprt9161-33gv.step 59 KB You want the bare part, or you mark your own boards.
tprt9161-33gv-etched.step 2.2 MB You want the part with TPRT9161-33GV already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 533 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: TECH PUBLIC datasheet (6 pp, sha256 9e364e521eff7220, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • 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).
