DS8242-33S3

DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

DS8242-33S3 from DSTECH, in a SOT-23-3. 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 GND power_in Ground return for the regulator. Connect to system ground with a wide, short trace back to the input and output capacitor ground pads for best performance.
2 VOUT power_out Regulated output of the LDO, fixed at 3.3V for the -33 option (±1% accuracy, up to 500mA load). Requires a ≥1µF output capacitor (1mΩ minimum ESR, 1µF-22µF effective capacitance) placed close to the pin.
3 VIN power_in Input supply voltage, operating range 2.0V to 24V (absolute max 30V). Requires a ≥1µF ceramic bypass capacitor to GND placed close to the pin.

CAD (KiCad official)

  • Symbol: DS8242-33S3
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: ds8242-33s3-etched.step / ds8242-33s3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ds8242-33s3.step / ds8242-33s3.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ds8242-33s3.step 59 KB You want the bare part, or you mark your own boards.
ds8242-33s3-etched.step 2.5 MB You want the part with DS8242-33S3 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 578 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: DSTECH datasheet (12 pp, sha256 02f10bfeea1c3ede, 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).
