Notes:
1. 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:
Input Output
Vin Vout
Capacitor Capacitor
3.3 VDC 4.7 µF 3.3 VDC 10.0 µF
5 VDC 4.7 µF 5 VDC 10.0 µF
12 VDC 2.2 µF 9 VDC 4.7 µF
12 VDC 2.2 µF
15 VDC 1.0 µF

For applications requiring very low output noise levels, Pin Description Pin Description
a simple LC filter should be effective.
5. It is recommended that a fuse be used on the input of 1 -Vin 5 +Vout
a power supply for protection. See the Model Selection 2 +Vin 6 NC
