This example is to supply 1.5A of current with a 10% margin. The equations in the red box can be solved to make a determination of the R_Limit resistor that would always supply the minimum current. The exercise is repeated based on a standard E96 resistor. The minimum current has been met but take care the maximum does not exceed 2.5A given the starting requirements. The last exercise is to make a determination of the impact of C_OUT. The idea is to make sure the capacitor will charge during the blanking period. In this case the capacitor does charge properly allowing the use of the A type device if desired. In a system setting the starting load and stray capacitance will also need consideration.
