n APPLICATION INFORMATIONS
A 1µF (or greater) capacitor is required between
the AIC1732 output and ground for stability.
Without this capacitor the part will oscillate. Even
though most types of capacitor may work, the
equivalent series resistance (ESR) should be held
to 5Ω or less if Aluminum electrolytic type is used.
Many Aluminum electrolytics have electrolytes
that freeze at about -30°C, so solid tantalums are
recommended for operation below -25°C. The
VOUT
GND
value of this capacitor may be increased without
limit.
A 0.1µF capacitor (or greater) should be placed
from the AIC1732 input to ground if the lead
inductance between the input and power source
exceeds 500nH (approximately 10 inches of trace).
