The AIC1730 provides factory-set output voltages
from 1.8V to 3.3V, in 100mV increments. The output
voltage is specified with V

load current and junction temperature. The dropout
voltage is specified at which the output voltage drops
100mV below the value measured with a 1V
difference.
DROPOUT VOLTAGE (V
DROP
)
The dropout voltage is defined as the difference
between the input voltage and output voltage at
which point the regulator starts to fall out of
regulation. Below this value, the output voltage will

)
Normal rated output current. This is limited by
