JW5250ASOTA#TR

JoulWatt Tech · DC-DC Converters · SOT-23-5

JW5250ASOTA#TR from JoulWatt Tech, 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 EN input Drive EN high to turn the regulator on and low to turn it off; the datasheet gives EN logic thresholds of 1.5V high (rising) and 0.4V low (falling), and shutdown is entered below 0.4V.
2 GND power_in Ground pin for the regulator.
3 SW output Switching node that supplies power to the output; connect the output LC filter from SW to the load.
4 VIN power_in Input voltage pin that supplies the IC; connect a 2.7V to 6.0V supply and bypass VIN to GND with a suitably large capacitor.
5 FB input Output feedback pin that senses the output through a resistive divider and is regulated by the control loop to 0.6V.

CAD (KiCad official)

  • Symbol: JW5250ASOTA#TR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: jw5250asota-tr-etched.step / jw5250asota-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); jw5250asota-tr.step / jw5250asota-tr.glb are the bare package body.
