1. 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.

The R1, R2 in the above table are used to set the output voltage. 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.
