Table 3 contains a list of manufacturers of the recommended capacitors. Ceramic capacitors will provide the
lowest output voltage ripple because they typically have the lowest ESR-rating.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
