The external resistor divider is used to set the output voltage. The feedback resistor (RFB1) cannot be too large or too small considering the trade-off for stability and dynamics. There is no strict requirement for the feedback resistor. RFB2 can be calculated with equation below. The values for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may slightly vary. ## Feedback Network |ct requirement for the feedback resistor.
