HT7333-1-MS

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

HT7333-1-MS from MSKSEMI, 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 GND power_in Ground reference (接地脚). Common return for input and output.
2 VIN power_in Unregulated supply input (输入端). Absolute max 24V, recommended >= VOUT + 1V. Decouple with a capacitor close to the pin.
3 VOUT power_out Regulated 3.3V output (输出端), up to 300 mA. Requires >= 2.2 uF capacitor to GND (tantalum recommended) for phase compensation via ESR.

Two STEP files. Same geometry, different body top:

File Size Use it when
ht7333-1-ms.step 59 KB You want the bare part, or you mark your own boards.
ht7333-1-ms-etched.step 1.7 MB You want the part with HT7333-1-MS already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 426 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: MSKSEMI datasheet (9 pp, sha256 30500dd371e5fb85, 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).
