The TC1240 and TC1240A are disabled when SHDN is
high, and enabled when SHDN is low. This input cannot
be allowed to float.

The most common application for charge pump
devices is the doubler (Figure 5-3). This application
uses two external capacitors – C
supply bypass capacitor, if necessary). The output is
equal to 2 x V
loading. Refer to Table 5-1 and Table 5-2 for capacitor
selection.
