1. For Vin ≤ 19V, and case temperatures ≥ 85°C, output voltage regulation is relaxed to -2.5%Vo,set.
2. When operating at output current between 0Adc and 1Adc, output ripple may exceed maximum pk-pk limits.
3. Use a minimum 2 x 220uF output capacitor. Recommended capacitor is Nichicon CD series, 220uF/35V. If the ambient
temperature is less than 0°C, use 3x of the minimum CO.
4. External capacitors may require using the new Tunable Loop™ feature to ensure that the module is stable as well as getting the
best transient response. See the Tunable Loop™ section for details.
