Tantalum chip capacitors are recommended for the input and output filter capacitors. A 22pF capacitor is suggested for the input filter capacitor. It should have a DC working voltage rat- ing higher than the maximum input voltage. A 68pF tantalum capacitor is suggested for the output capacitor. The DC working voltage rating should be greater than the output volt- age. Very high ESR values (>3 1 ) should be avoided. Table 7 shows a list of the capacitor manufacturers.
