Notes:
1. Output load regulation is specified for a load change
of 20% to 100%.
2. When measuring output ripple, it is recommended
that an external 0.33 μF ceramic capacitor be placed
from the +Vout pin to the -Vout pin.
3. Operation at no-load will not damage these units.
However, they may not meet all specifications.
4. These do not require external components to operate,
but the use of a low ESR capacitor (approximately
10 uF, ESR <1.0Ω at 100 kHz) mounted close to the
converter input pins is recommended.
5. It is recommended that a fuse be used on the input of
a power supply for protection. See the table above for
the correct rating.
