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.
