Table 3. Recommended Values for CPU-based Applications
* Output capacitance requirements depend critically on layout and processor type. Consult Application Bulletin AB-14 for details.
See the Appendix to this datasheet for the method of calculation of these components. Pin 4 must be used to remote sense
the voltage at the processor to achieve the specified performance.
