LSF0204: Current need for VREF-B Supply for 2.5V rail

Joey Yuen

Part Number: LSF0204


Hi Team,

The LSF0204 is used to convert between 1.0V and 1.8V.  The customer is using 2.5V as Vref_B since we recommend the device has 1V higher for Vref-B than Vref-A.

The pull up resistors are connected to 1.8V.  (422 Ohm)

The customer is asking how much current is needed for Vref-B supply for the 2.5V power rail in usage case described above?

Thanks,

Joey
