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. 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: Derating Curve Vin 5 VDC 12 VDC Input Capacitor 4.7 µF 2.2 µF Vout 5 VDC 9 VDC 12 VDC 15 VDC Output Capacitor 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. See the Model Selection table above for the correct rating.
