Output load regulation is speciﬁed for a load change of 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 for single output units and from each output to common for dual output units. 3. During operation, care must be taken not to exceed the speciﬁed input range of the unit or to allow the output load to drop below the speciﬁed minimum (10% of full load). Operating the unit under either of these conditions could cause damage to the unit. 4. These converters are speciﬁed for operation without external components. However, in some applications the addition of input/output capacitors will enhance stability and reduce output ripple. Recommended capacitor values are: Vin Input Capacitor Vout Output Capacitor Derating Curve 3.3 VDC 5 VDC 12 VDC 10.0 µF 4.7 µF 2.2 µF 5 VDC 9 VDC 12 VDC 15 VDC 4.7 µF 2.2 µF 1.0 µF 0.47 µF 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.
