Part Number: TPS62230
We will use TPS62233 regulator in our PCB. You now, there are three components of this regulator.We selected 4.7uF for CIN, 4.7uF for COUT and 2.2uH for L. We did 0402 footprints on our PCB for these components. But there are components with 0805 package in regulator's datasheet as recommendation.Which components must we use with 0402 footprint for my PCB and What are their Digikey or Mouser Links for order?
Thanks and best regards,

Thanks for reply,
We selected Murata GRM155R60J475ME87D for CIN and COUT. Beacuse our VIN is 3,6V and our VOUT is 2,5V. Therefore 6,3DC rated capacitor is enough for us. Murata GRM155R60J475ME87D has got 0402 footprint.
Now we search 2.2uH inductor with 0402 footprint for regulator. I calculated ILmax. Its value is 557mA. Therefore, I must find inductor which has got saturation current higger than 557mA. It should have 0402 footprint. Can we find inductor with these features?
