C1 and C2 are required for best performance and should be fitted close to the converter pins. 2. See the capacitor values for C1 and C2 in the external capacitor table below. These can be increased if required and tantalum or low ESR electrolytic capacitors will also suffice. 3. No parallel connection or plug and play.

If no need to adjust the output voltage, connect a ceramic capacitor to GND with 470pF typical value for increase immunity. Insure the output voltage is in the adjust range or else may cause permanent damage to the device. Fine-tune output voltage must appease Vin-Vo>2V.
