DS8241-50S5

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

DS8241-50S5 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 the absolute maximum VIN to GND is 30V.
2 GND power_in Ground reference pin for the regulator; input and output capacitor grounds should return to this pin through short, wide traces.
3 EN input Enable control input; pulling EN low puts the regulator into shutdown (typical shutdown ground current 0.1µA), with EN thresholds of 1.1V rising and 0.4V falling.
4 NC unconnected No internal connection on the DS8241 (non-N) variant; the SNS sense function on pin 4 applies only to the DS8241N.
5 VOUT power_out Output of the regulator; for the 5.0V option (-50) it is a fixed 5.0V output, with output current limit of 700mA typical and absolute maximum VOUT to GND of 6V.

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: DS8241-50S5
  • 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: ds8241-50s5-etched.step / ds8241-50s5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ds8241-50s5.step / ds8241-50s5.glb are the bare package body.
