DS8571-18S5

DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

DS8571-18S5 from DSTECH, in a SOT-23-5. 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 datasheet gives a recommended input range of 2.3V to 6V, with an absolute maximum of -0.3V to 7V to GND.
2 GND power_in Ground reference for the regulator; input and output capacitor ground connections should return to this pin through short, wide copper traces.
3 EN input Enable control input; the datasheet gives an EN rising threshold (VIH) of 1.0V and a falling threshold (VIL) of 0.4V, with an absolute maximum of -0.3V to 6V to GND.
4 NC unconnected No internal connection on the DS8571 (non-SNS) SOT-23-5 variant.
5 VOUT power_out Output of the regulator, rated up to 300mA output current, with an absolute maximum of -0.3V to 6V to GND.

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 DS8571 ground pin using as wide and as short of a copper trace as is practical. 12

CAD (KiCad official)

  • Symbol: DS8571-18S5
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ds8571-18s5-etched.step / ds8571-18s5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ds8571-18s5.step / ds8571-18s5.glb are the bare package body.
