on no-load supply current. Schottky diodes such as
MBR0530, BAS85 and BAT84 work well. Another more
serious effect of the protection diode leakage is that at no
load with nothing to provide a sink for this leakage
current, the output voltage can potentially float above the

occuring, a resistor must be connected between V

possible leakage current.
