8.2.2.1 Capacitor Selection

To maintain the lowest output resistance, use capacitors with low ESR (see Table 8-1). The charge-pump output resistance is a function of C(fly) and CO ESR. Therefore, minimizing the ESR of the charge-pump capacitors minimizes the total output resistance. The capacitor values are closely linked to the required output current and the output noise and ripple requirements. Only using 1µF capacitors of the same type is possible. Ceramic capacitors provide the lowest output voltage ripple because ceramic capacitors typically have the lowest ESR-rating.
