RBB10-2.0-EVM-1
OUTPUT VOLTAGE TRIMMING
The RBB10-2.0 series offers the feature of trimming the output voltage over a range between 1.0V and 5.5V by using external trim resistors.
The values for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may slightly vary.
