*The 2.2 pF cap can be placed at the same point
as the 1.2 nH inductor which should be as close as
possible to the DC blocking cap (8 pF) or it can be
1 nF
330 pF
placed up to 25 mils away from the inductor for the
best linear performance.

O NOTES:
1. For VREG that is higher than the nominal voltage specified, a resistor bridge can be used to drop the voltage for VREG
to the appropriate level needed at the pins.
