(1) All typical values are at TA = 25°C.
(2) Measured by the voltage drop between the A and B terminals at the indicated current through the switch. On-state resistance is determined by the lowest voltage of the two (A or B) terminals.
(3) The actual supply current for LSF0204 is ICCA + ICCB; the leakage from Vref_B to Vref_A can be measured on Vref_A and Vref_B pin
