RON 75 k for V = 5 V OUT The additional aluminium electrolytic capacitor C1 is only for evaluation board protection purposes. It is mounted at the termination R1 0 resistor bridge To be soldered for adjustable frequency of the supply line and provides slight damping of possible oscillations of the series resonance circuit represented by the RENT 124 k inductance of the supply line and the input capacitance. It is not essential for operation.
