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 is changed from V
V
LOAD REGULATION
Load regulation is the ability of the regulator to
maintain a constant output voltage as the load
current changes. To minimize temperature effects, it
is a pulsed measurement with the input voltage set to
V
under the output current step of 0.1mA to 150mA.
QUIESCENT CURRENT (I
The quiescent current is the current flowing through
the ground pin under no load.
GROUND CURRENT (I
Ground current is the current flowing through the
ground pin under loading.
STANDBY CURRENT (I
Standby current is the current flowing into the
regulator when the output is shutdown by setting
V SHDN = 0V, V
CURRENT LIMIT (I
The AIC1730 include a current limiter, which
monitors and controls the maximum output current to
be 300mA typically if the output is shorted to ground.
This can protect the device from being damaged.

THERMAL PROTECTION
The thermal sensor protects the device when the
junction temperature exceeds T
the shutdown logic, turning off the pass transistor
and allowing the IC to cool. After the IC’s junction
temperature cools by 15ºC, the thermal sensor will
turn on the pass transistor again. Thermal protection
is designed to protect the device in the event of fault
conditions. For continuous operation do not exceed
the absolute maximum junction-temperature rating of
T
J
= 150ºC, or damage may occur to the device.
APPLICATION INFORMATION
INPUT-OUTPUT CAPACITORS
Linear regulators require input and output
capacitors
recommended minimum value of input capacitor
is 0.22 F. The output capacitor should be
selected within the Equivalent Series Resistance
(ESR) range shown in the graphs below for
stability. Because the ceramic capacitor’s ESR is
lower
(capacitance
temperature, a tantalum output capacitor is
recommended, especially for heavier load. In
general, the capacitor should be at least
1 F(tantalum) and be rated for the actual
ambient operating temperature range.
Note: It is very important to check the selected
manufactures’
