9.Place the switching MOSFET as close to the +5.0 V

input capacitors as possible.

10. Place the output capacitors as close to the load as

possible.

11. Place the VFB, VOUT filter resistors (510 Ω) in series

with the VFB and VOUT pins as close as possible to the

pins.

12. Place the COFF and COMP capacitors as close as

possible to the COFF and COMP pins.

13. Place the current limit filter capacitor between the

VFB and VOUT pins, as close as possible to the pins.

14. Connect the filter components of the following pins:

VFB, VOUT, COFF, and COMP to the GND pin with a

single trace, and connect this local GND trace to the

output capacitor GND.

15. The “Droop” Resistor (embedded PCB trace) has to

be wide enough to carry the full load current.

16. Place the VCC bypass capacitor as close as possible to

the IC.
