DS8404-50A3

DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

DS8404-50A3 from DSTECH, in a SOT-89-3. 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, recommended 2.5V to 36V (absolute maximum 40V), with a 1uF or larger input capacitor placed close to VIN and GND.
2 GND power_in Ground pin; input and output capacitor grounds should return to it with short, wide copper traces.
3 VOUT power_out Regulated 5.0V output (DS8404-50) for up to 500mA peak load current, absolute maximum 14V to GND, requiring an output capacitor of 1uF to 22uF.

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 DS8404 ground pin using as wide and as short of a copper trace as is practical. 9

CAD (KiCad official)

  • Symbol: DS8404-50A3
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: ds8404-50a3-etched.step / ds8404-50a3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ds8404-50a3.step / ds8404-50a3.glb are the bare package body.
