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. |
