APPLICATION INFORMATION
High current applications are described in Table 6. The values are recommendations based on actual test
circuits. Many variations are possible based on the requirements of the user. Performance of the circuit is
dependent upon the layout rather than on the specific components, if the device parameters are not exceeded.
The power stage, having the highest current levels and greatest dv/dt rates, should be given the most attention,
as both the supply and load can be severely affected by the power levels and edge rates.
