DS8367-50A3

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

DS8367-50A3 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 GND power_in Ground reference for the regulator; the input and output capacitor ground connections must return to this pin using as wide and short a copper trace as practical.
2 VIN power_in Input of supply voltage, specified from 2V to 36V, with a 1µF or larger input capacitor placed close to the VIN and GND pins.
3 VOUT power_out Output of the regulator, which is current-limited to 300mA typical and can be shorted to ground indefinitely without damage.

CAD (KiCad official)

  • Symbol: DS8367-50A3
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: ds8367-50a3-etched.step / ds8367-50a3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ds8367-50a3.step / ds8367-50a3.glb are the bare package body.
