DS8241-33S5

DSTECH · Linear Voltage Regulators (LDO) · SOT23-5

DS8241-33S5 from DSTECH, in a SOT23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Input of supply voltage; the recommended operating input range is 2.0V to 24V, and a 1µF or larger input capacitor should be placed close to VIN and GND.
2 GND power_in Ground reference for the regulator.
3 EN input Enable control input; pulling EN low puts the regulator into shutdown, with a typical shutdown current of 100nA.
4 NC unconnected No internal connection on this variant.
5 VOUT power_out Output of the regulator; fixed 3.3V output for this -33 variant, with ±1% output accuracy and 500mA maximum output current.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts copper must be back to the DS8241 ground pin using as wide and as short of a copper trace as is practical. 9

CAD (KiCad official)

  • Symbol: DS8241-33S5
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT23-5, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.092 mm tall, datasheet A, midpoint of min and max). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: ds8241-33s5-etched.step / ds8241-33s5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ds8241-33s5.step / ds8241-33s5.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: DSTECH datasheet (10 pp, sha256 ee710bf2d6fa8407, retrieved 2026-11-12, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
