Minimum

load

The minimum load to meet datasheet specification is 10% of the full rated load across the specified input voltage range. Lower than 10% minimum loading

will result in an increase in output voltage, which may rise to typically double the specified output voltage if the output load falls to less than 5%.

Capacitive

up

Typical start up times for this series, with a typical input voltage rise time of 2.2s and output capacitance of 10F, are shown in the table below. The product

series will start into a capacitance of 47F with an increased start time, however, the maximum recommended output capacitance is 10F.

Tolerance

envelope

The voltage tolerance envelope shows typical load regulation characteristics for this

product series. The tolerance envelope is the maximum output voltage variation due

to changes in output loading.
