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.
