DESCRIPTION
The AIC1714 is a series of 3-terminal negative
voltage regulators with output voltages
internally set below the positive supply voltage.
Since the AIC1714 consumes less current and
only requires a small input/output voltage
difference than existing industry standard 3-
terminal voltage regulators, a battery-powered
portable equipment is afforded a high capacity
and longer service life. The AIC1714 is ideal for
power source of liquid crystal displays.

APPLICATION INFORMATIONS
A 1
F (or greater) capacitor is required between
the AIC1714 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 5
or less if Aluminum electrolytic type is used.
Many Aluminum electrolytic have electrolytes that
freeze at about -30
C, so solid tantalums are
recommended for operation below -25
C. The
value of this capacitor may be increased without
limit.
A 0.1
F capacitor (or greater) should be placed
from the AIC1714 input to ground if the lead
inductance between the input and power source
exceeds 500nH (approximately 10 inches of trace).
