C1, C2, C3, C4 = 10 nF
(These capacitors must be
placed very close to their
respective IC pins)
C5, C6, C7 = 33 µF
(Low ESR and ESL
capacitors are
recommended)
C8 = 10 µF
C9, C0 = 1 µF
R1 = 500 Ω
VSSA plane must be
different from other
ground plane
3 V, 3 A must be a
low-noise supply and
separate from
other supplies
