2.4
On “F” devices, a low-ESR (< 5Ω) capacitor is required
on the V
regulator output voltage. The V
not be connected to V
an “F” device. The V
connected to a 10 µF capacitor to ground. The type can
be ceramic or tantalum. Suitable example capacitors
are provided in
Designers may use
equivalence of candidate devices. It is recommended
that the trace length not exceed 0.25 inch (6 mm).
Refer to
additional information.
On “LF” devices, the internal core voltage regulator is
disabled. On these devices, the V
must be externally connected to a suitable V
level voltage source at the circuit board level. Refer to
Section 30.0 “Electrical Characteristics”
allowed V
bypassing practices should be used for the supply
source providing the V
