Notes:
1. Output load regulation is specified for a load change of
Derating Curve
10% 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. These units should not be operated with a load under
10% of full load. Operation at no-load may cause damage
to the unit.
4. These converters are specified for operation without
external components. However, in some applications the
addition of input/ouput capacitors will enhance stability
and reduce output ripple. Recommended capacitor values
are:
Input Output
Vin Vout
Capacitor Capacitor
5 VDC 4.7 µF 3.3 VDC 10.0 µF
12 VDC 2.2 µF 5 VDC 10.0 µF
24 VDC 1.0 µF 9 VDC 4.7 µF
12 VDC 2.2 µF
15 VDC 1.0 µF
24 VDC 1.0 µF Mechanical Dimensions
For applications requiring very low output noise levels,
a simple LC filter should be effective.
5. It is recommended that a fuse be used on the input of
a power supply for protection. See the Model Selection
table above for the correct rating.
