Application Information (Continued)
value, smaller size capacitor usually has a higher ESR com-
pared with a bigger size capacitor of the same type. For
lower ESR, use ceramic capacitors.

PARALLELING DEVICES
Any number of LM2660s (or LM2661s) can be paralleled to
reduce the output resistance. Each device must have its own
pumping capacitor C
1, while only one output capacitor Cout is
needed as shown in Figure 4. The composite output resis-
tance is:
