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

Other Applications
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 C
out
is needed as shown in Figure 4 The composite output resistance is:
