n DETAILED DESCRIPTION OF TECHNICAL TERMS
fall as the input voltage is reduced. It depends on the
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.
OUTPUT VOLTAGE (VOUT
)
The AIC1730 provides factory-set output voltages
from 1.8V to 3.3V, in 100mV increments. The output
voltage is specified with V = VOUT (TYP) + 1V and
IN
IOUT = 0mA
CONTINUOUS OUTPUT CURRENT (IOUT
)
DROPOUT VOLTAGE (VDROP
)
Normal rated output current. This is limited by
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
package power dissipation.
