500mA, Low Dropout Linear Regulator with Shutdown
ꢀFEATURES
ꢀDESCRIPTION
ꢁ Active Low Shutdown Control.
ꢁ Very Low Quiescent Current.
AIC1733 is a 500mA low noise, low dropout
linear regulator, and is housed in small SOT-23-5
package. The device is in the “ON” state when
ꢁ Very Low Dropout Voltage of 650mV at 500mA
Output Current (3.0V Output Version)
ꢁ 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V Output Voltage.
ꢁ Short Circuit and Thermal Protection.
ꢁ ±2% Output Tolerance.
the SHDN pin is set to logic high level. An
internal P-MOSFET pass transistor is used to
achieve 650mV low dropout voltage at 500mA
load current. It offers high precision output
ꢁ Miniature Package: SOT-23-5
voltage of ±2%. The quality of low quiescent
current and low dropout voltage makes this
device ideal for battery power applications. The
internal reverse bias protection eliminates the
requirement for a reverse voltage protection
diode. The high ripple rejection and low noise of
AIC1733 provide enhanced performance for
critical applications. The noise bypass pin can be
connected an external capacitor to reduce the
output noise level.

DROPOUT VOLTAGE (VDROP
)
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.
LOAD REGULATION
Load regulation is the ability of the regulator to
maintain a constant output voltage as the load
current changes. A pulsed measurement with an
input voltage set to VIN = VOUT + VDROP can
minimize temperature effects. The load regulation
is specified by the output current ranging from
0.1mA to 500mA.
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

AIC1733
CURRENT LIMIT (IIL)
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 TJ=
150ºC, or damage may occur to the device.
AIC1733 includes a current limiting, which
monitors and controls the maximum output
current if the output is shorted to ground. This
can protect the device from being damaged.
THERMAL PROTECTION
Thermal sensor protects device when the
junction temperature exceeds TJ= +155ºC. It
ꢀAPPLICATION INFORMATION
INPUT-OUTPUT CAPACITORS
large power dissipation applies.
The power dissipation across the device is
P = IOUT (VIN-VOUT).
Linear regulators require input and output
capacitors to maintain stability. Input capacitor at
1µF with a 4.7uF aluminum electrolytic output
capacitor is recommended. To avoid oscillation,
ceramic capacitor is rejected.
The maximum power dissipation is:
(TJ − TA)
(RθJB + RθBA)
PMAX =
Where TJ-TA is the temperature difference
between the die junction and the surrounding air,
RθJB is the thermal resistance of the package,
and RθBA is the thermal resistance through the
PCB, copper traces, and other materials to the
surrounding air.
NOISE BYPASS CAPACITOR
0.1µF bypass capacitor at BP pin reduces output
voltage noise. And the BP pin has to connect a
capacitor to GND.
POWER DISSIPATION
As a general rule, the lower temperature is, the
better reliability of the device is. So the PCB
mounting pad should provide maximum thermal
conductivity to maintain low device temperature.
GND pin performs a dual function of providing
an electrical connection to ground and
channeling heat away. Therefore, connecting
the GND pin to ground with a large pad or
ground plane would increase the power
dissipation and reduce the device temperature
The maximum power dissipation of AIC1733
depends on the thermal resistance of its case
and circuit board, the temperature difference
between the die junction and ambient air, and
the rate of airflow. The rate of temperature rise is
greatly affected by the mounting pad
configuration on the PCB, the board material,
and the ambient temperature. When the IC
mounting with good thermal conductivity is used,
the junction temperature will be low even when
