Notes:
1. Inductor L1 is recommended to isolate the 5V input supply from noise generated by the MOSFET switching, and to comply
2. For designs using the TO-220 MOSFETs, heatsinks with thermal resistance
*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 5 must be used to remote sense the
voltage at the processor to achieve the specified performance.
