DROPOUT VOLTAGE (V
DROP
)
The dropout voltage is defined as the difference
between the input voltage and output voltage at
which the output voltage drops 100mV. Below
this value, the output voltage will fall as the input
voltage reduces. It depends on the load current
and junction temperature.
LINE REGULATION
Line regulation is the ability of the regulator to
maintain a constant output voltage as the input
voltage changes. The line regulation is specified
as the input voltage changes from V
IN
= V
OUT
+
1V to V
IN
= 8V and I
OUT
= 1mA.
LOAD REGULATION
Load regulation is the ability of the regulator to
maintain a constant output voltage as the load
current changes.

input voltage set to V

effects.
The
load
QUIESCENT CURRENT (I
Q
)
Quiescent current is the current flowing through
ground pin with no output load.
GROUND CURRENT (I
GND
)
Ground current is the current flowing through the
ground pin with output load.
STANDBY CURRENT (I
STBY
)
Standby current is the current flowing into the
regulator when the output is shutdown by setting
V
SHDN
at 0V and V
IN
at 8 V.
CURRENT LIMIT (I
IL
)
Current limiting of AIC1742 monitors and controls
the maximum output current, in case of a shorted
output. It protects device from the damage
resulting from any unexpected current.
RIPPLE REJECTION (RR)
Ripple rejection is the ability of the regulator to
reduce voltage ripple, which comes from input, at
output terminal. It is specified with a signal of
0.5V
P-P
at 1KHz frequency applying to input,
output capacitor at 2.2
μ
F as well as a noise
bypass of 0.1
μ
F. Ripple rejection, expressed in
dB, is the ratio of output ripple to input.
THERMAL PROTECTION
Thermal sensor protects device when the
junction temperature exceeds T
J
= +155oC. It
signals shutdown logic, turning off pass transistor
and allowing IC to cool down. After the IC’s
junction temperature cools by 15oC, the thermal
sensor will turn the pass transistor back on.
Thermal protection is designed to protect the
device in the event of fault conditions. For a
continuous operation, do not exceed the absolute
maximum junction-temperature rating of T
J
=
150oC, or damage may occur to the device.
