LINE REGULATION
The percentage change in output voltage between low input voltage and high input voltage,
measured with fixed output load
ie. A 5V output part with an output voltage of 5.05V @ high input voltage and 5.03V @
low input voltage would have a line regulation of 0.4%.

EXTERNAL CAPACITANCE
Although these converters will work
without external capacitors, they are
necessary in order to guarantee the full
parametric performance over the
full line and load range. All parts have
been tested and characterised
using the following values and test circuit
