Output AC characteristics

The definition and values of output AC characteristics are given in Figure 35: Output AC

characteristics definition and in the table below respectively.

Unless otherwise specified, the parameters given are derived from tests performed under

the ambient temperature and supply voltage conditions summarized in Table 32.
