AAT3200
OmniPower™ LDO Linear Regulator
General Description
Features
The AAT3200 PowerLinear OmniPower low
dropout (LDO) linear regulator is ideal for systems
where a low-cost solution is required. This device
features extremely low quiescent current, typically
20µA. Dropout voltage is also very low, typically
200mV. The AAT3200 has output short-circuit and
over-current protection. In addition, the device has
an over-temperature protection circuit which will
shut down the LDO regulator during extended
over-current events.

The AAT3200 is available in a space-saving, Pbfree SC59 or SOT-89 package (for applications
requiring increased power dissipation). The device
is rated over a -40°C to +85°C temperature range.
Since only a small, 1µF ceramic output capacitor is
required, the AAT3200 is a truly cost-effective voltage conversion solution.
The AAT3201 is a similar product for this application, especially when a shutdown mode is required
for further power savings.

Functional Description
The AAT3200 is intended for LDO regulator applications where output current load requirements
range from no load to 150mA for an SC59 package,
or 250mA for a SOT-89 package.
The advanced circuit design of the AAT3200 has
been optimized for use as the most cost-effective
solution. The typical quiescent current level is
just 20µA and it does not increase with increasing
current load. The LDO also demonstrates excellent PSRR and load and line transient response
characteristics.
8
The LDO regulator output has been specifically
optimized to function with low-cost, low-ESR
ceramic capacitors. However, the design will allow
for operation with a wide range of capacitor types.
The AAT3200 has complete short-circuit and thermal protection. The integral combination of these
two internal protection circuits gives the AAT3200 a
comprehensive safety system to guard against
extreme adverse operating conditions. Device
power dissipation is limited to the package type and
thermal dissipation properties. Refer to the Thermal
Considerations section of this datasheet for details
on device operation at maximum output load levels.
3200.2006.02.1.4
AAT3200
OmniPower™ LDO Linear Regulator
Applications Information
To assure the maximum possible performance is
obtained from the AAT3200, please refer to the following application recommendations.
Input Capacitor
Typically, a 1µF or larger capacitor is recommended
for CIN in most applications. A CIN capacitor is not
required for basic LDO regulator operation.
However, if the AAT3200 is physically located any
distance more than one or two centimeters from the
input power source, a CIN capacitor will be needed
for stable operation. CIN should be located as
closely to the device VIN pin as practically possible.
CIN values greater than 1µF will offer superior input
line transient response and will assist in maximizing
the highest possible power supply ripple rejection.
Ceramic, tantalum, or aluminum electrolytic capacitors may be selected for CIN. There is no specific
capacitor equivalent series resistance (ESR)
requirement for CIN. For 150mA to 250mA LDO regulator output operation, ceramic capacitors are recommended for CIN due to their inherent capability
over tantalum capacitors to withstand input current
surges from low impedance sources such as batteries in portable devices.
Output Capacitor
For proper load voltage regulation and operational
stability, a capacitor is required between pins VOUT
and GND. The COUT capacitor connection to the
LDO regulator ground pin should be made as direct
as practically possible for maximum device performance. The AAT3200 has been specifically
designed to function with very low ESR ceramic
capacitors. Although the device is intended to operate with low ESR capacitors, it is stable over a wide
range of capacitor ESR; thus, it will also work with
some higher ESR tantalum or aluminum electrolytic
capacitors. However, for best performance, ceramic capacitors are recommended.
The value of COUT typically ranges from 0.47µF to
10µF; however, 1µF is sufficient for most operating
conditions.
3200.2006.02.1.4
If large output current steps are required by an
application, then an increased value for COUT
should be considered. The amount of capacitance
needed can be calculated from the step size of the
change in the output load current expected and the
voltage excursion that the load can tolerate.
The total output capacitance required can be calculated using the following formula:
COUT =
∆I
× 15µF
∆V
Where:
∆I = maximum step in output current
∆V = maximum excursion in voltage that the load
can tolerate
Note that use of this equation results in capacitor
values approximately two to four times the typical
value needed for an AAT3200 at room temperature.
The increased capacitor value is recommended if
tight output tolerances must be maintained over
extreme operating conditions and maximum operational temperature excursions. If tantalum or aluminum electrolytic capacitors are used, the capacitor value should be increased to compensate for the
substantial ESR inherent to these capacitor types.
Capacitor Characteristics
Ceramic composition capacitors are highly recommended over all other types of capacitors for use
with the AAT3200. Ceramic capacitors offer many
advantages over their tantalum and aluminum electrolytic counterparts. A ceramic capacitor typically
has very low ESR, is lower cost, has a smaller PCB
footprint, and is non-polarized. Line and load transient response of the LDO regulator is improved by
using low ESR ceramic capacitors. Since ceramic
capacitors are non-polarized, they are less prone
to damage if incorrectly connected.
Equivalent Series Resistance: ESR is a very
important characteristic to consider when selecting
a capacitor. ESR is the internal series resistance
associated with a capacitor that includes lead
9
AAT3200
OmniPower™ LDO Linear Regulator
resistance, internal connections, capacitor size and
area, material composition, and ambient temperature. Typically, capacitor ESR is measured in milliohms for ceramic capacitors and can range to
more than several ohms for tantalum or aluminum
electrolytic capacitors.
Ceramic Capacitor Materials: Ceramic capacitors
less than 0.1µF are typically made from NPO or C0G
materials. NPO and C0G materials generally have
tight tolerance and are very stable over temperature.
Larger capacitor values are usually composed of
X7R, X5R, Z5U, or Y5V dielectric materials. Large
ceramic capacitors (i.e., greater than 2.2µF) are
often available in low-cost Y5V and Z5U dielectrics.
These two material types are not recommended for
use with LDO regulators since the capacitor tolerance can vary by more than ±50% over the operating temperature range of the device. A 2.2µF Y5V
capacitor could be reduced to 1µF over the full operating temperature range. This can cause problems
for circuit operation and stability. X7R and X5R
dielectrics are much more desirable. The temperature tolerance of X7R dielectric is better than ±15%.
Capacitor area is another contributor to ESR.
Capacitors that are physically large in size will have
a lower ESR when compared to a smaller sized
capacitor of equivalent material and capacitance
value. These larger devices can also improve circuit transient response when compared to an equal
value capacitor in a smaller package size.
Consult capacitor vendor datasheets carefully when
selecting capacitors for use with LDO regulators.
Short-Circuit and Thermal Protection
The AAT3200 is protected by both current limit and
over-temperature protection circuitry. The internal
short-circuit current limit is designed to activate
when the output load demand exceeds the maximum rated output. If a short-circuit condition were
to continually draw more than the current limit
threshold, the LDO regulator output voltage would
drop to a level necessary to supply the current
demanded by the load. Under short-circuit or other
10
over-current operating conditions, the output voltage would drop and the AAT3200 die temperature
would increase rapidly. Once the regulator's power
dissipation capacity has been exceeded and the
internal die temperature reaches approximately
140°C, the system thermal protection circuit will
become active. The internal thermal protection circuit will actively turn off the LDO regulator output
pass device to prevent the possibility of over-temperature damage. The LDO regulator output will
remain in a shutdown state until the internal die
temperature falls back below the 140°C trip point.
The combination and interaction between the shortcircuit and thermal protection systems allows the
LDO regulator to withstand indefinite short-circuit
conditions without sustaining permanent damage.
No-Load Stability
The AAT3200 is designed to maintain output voltage regulation and stability under operational noload conditions. This is an important characteristic
for applications where the output current may drop
to zero. An output capacitor is required for stability
under no-load operating conditions. Refer to the
Output Capacitor section of this datasheet for recommended typical output capacitor values.
Thermal Considerations and High
Output Current Applications
The AAT3200 is designed to deliver a continuous
output load current of 150mA for an SC59 package
or 250mA for a SOT-89 package under normal
operating conditions. The limiting characteristic for
the maximum output load safe operating area is
essentially package power dissipation and the
internal preset thermal limit of the device. In order
to obtain high operating currents, careful device
layout and circuit operating conditions need to be
taken into account. The following discussions will
assume the LDO regulator is mounted on a printed
circuit board utilizing the minimum recommended
footprint and the printed circuit board is 0.062-inch
thick FR4 material with one ounce copper.
3200.2006.02.1.4
AAT3200
OmniPower™ LDO Linear Regulator
At any given ambient temperature (TA), the maximum package power dissipation can be determined by the following equation:
This formula can be solved for VIN to determine the
maximum input voltage.
VIN(MAX) =
-T
T
PD(MAX) = J(MAX) A
θJA
Constants for the AAT3200 are TJ(MAX), the maximum junction temperature for the device (125°C)
and ΘJA = 200°C/W, the SC59 thermal resistance.
Typically, maximum conditions are calculated at the
maximum operating temperature where TA = 85°C,
under normal ambient conditions TA = 25°C. Given
TA = 85°C, the maximum package power dissipation is 200mW. At TA = 25°C, the maximum package power dissipation is 500mW.
The maximum continuous output current for the
AAT3200 is a function of the package power dissipation and the input-to-output voltage drop across
the LDO regulator. Refer to the following simple
equation:
IOUT(MAX) <
PD(MAX)
VIN - VOUT
For example, if VIN = 5V, VOUT = 3V, and TA = 25°C,
IOUT(MAX) < 250mA. The output short-circuit protection threshold is set between 150mA and 300mA.
If the output load current were to exceed 250mA or
if the ambient temperature were to increase, the
internal die temperature will increase. If the condition remained constant and the short-circuit protection were not to activate, there would be a potential
damage hazard to LDO regulator since the thermal
protection circuit will only activate after a short-circuit event occurs on the LDO regulator output.
To determine the maximum input voltage for a
given load current, refer to the following equation.
This calculation accounts for the total power dissipation of the LDO regulator, including that caused
by ground current.
PD(MAX) = (VIN - VOUT)IOUT + (VIN × IGND)
3200.2006.02.1.4
PD(MAX) + (VOUT × IOUT)
IOUT + IGND
The following is an example for an AAT3200 set for
a 3.0V output:
From the discussion above, PD(MAX) was determined to equal 417mW at TA = 25°C.
VOUT
= 3.0V
IOUT
= 150mA
IGND
= 20µA
VIN(MAX) =
500mW + (3.0V × 150mA)
150mA + 20µA
VIN(MAX) > 5.5V
Thus, the AAT3200 can sustain a constant 3.0V
output at a 150mA load current as long as VIN is ≤
5.5V at an ambient temperature of 25°C. 5.5V is
the maximum input operating voltage for the
AAT3200, thus at 25°C, the device would not have
any thermal concerns or operational VIN(MAX) limits.
This situation can be different at 85°C. The following is an example for an AAT3200 set for a 3.0V
output at 85°C:
From the discussion above, PD(MAX) was determined to equal 200mW at TA = 85°C.
VOUT
= 3.0V
IOUT
= 150mA
IGND
= 20µA
VIN(MAX) =
200mW + (3.0V × 150mA)
150mA + 20µA
VIN(MAX) = 4.33V
11
AAT3200
OmniPower™ LDO Linear Regulator
For example, an application requires VIN = 5.0V
while VOUT = 3.0V at a 150mA load and TA = 85°C.
VIN is greater than 4.33V, which is the maximum
safe continuous input level for VOUT = 3.0V at
150mA for TA = 85°C. To maintain this high input
voltage and output current level, the LDO regulator
must be operated in a duty-cycled mode. Refer to
the following calculation for duty-cycle operation:

Voltage Drop (V)
Higher input-to-output voltage differentials can be
obtained with the AAT3200, while maintaining
device functions in the thermal safe operating area.
To accomplish this, the device thermal resistance
must be reduced by increasing the heat sink area
or by operating the LDO regulator in a duty-cycled
mode.

High Peak Output Current Applications
Some applications require the LDO regulator to
operate at continuous nominal levels with short
duration, high-current peaks. The duty cycles for
both output current levels must be taken into
account. To do so, one would first need to calculate the power dissipation at the nominal continuous level, then factor in the addition power dissipation due to the short duration, high-current
peaks.
For example, a 3.0V system using a AAT3200IGV2.5-T1 operates at a continuous 100mA load current level and has short 150mA current peaks. The
current peak occurs for 378µs out of a 4.61ms period. It will be assumed the input voltage is 5.0V.
First, the current duty cycle percentage must be
calculated:
% Peak Duty Cycle: X/100 = 378µs/4.61ms
% Peak Duty Cycle = 8.2%
The LDO regulator will be under the 100mA load for
91.8% of the 4.61ms period and have 150mA peaks
occurring for 8.2% of the time. Next, the continuous
nominal power dissipation for the 100mA load should
be determined then multiplied by the duty cycle to
conclude the actual power dissipation over time.
PD(MAX) = (VIN - VOUT)IOUT + (VIN x IGND)
PD(100mA) = (4.2V - 3.0V)100mA + (4.2V x 20µA)
PD(100mA) = 120mW
PD(91.8%D/C) = %DC x PD(100mA)
PD(91.8%D/C) = 0.918 x 120mW
PD(91.8%D/C) = 110.2mW
The power dissipation for 100mA load occurring for
91.8% of the duty cycle will be 110.2mW. Now the
power dissipation for the remaining 8.2% of the
duty cycle at the 150mA load can be calculated:
PD(8.2%D/C) = %DC x PD(150mA)
PD(8.2%D/C) = 0.082 x 180mW
PD(8.2%D/C) = 14.8mW
The power dissipation for a 150mA load occurring
for 8.2% of the duty cycle will be 14.8mW. Finally,
the two power dissipation levels can be summed to
determine the total power dissipation under the
varied load.
PD(total) = PD(100mA) + PD(150mA)
PD(total) = 110.2mW + 14.8mW
PD(total) = 125.0mW
The maximum power dissipation for the AAT3200
operating at an ambient temperature of 85°C is
200mW. The device in this example will have a
total power dissipation of 125.0mW. This is well
within the thermal limits for safe operation of the
device.
Printed Circuit Board Layout
Recommendations
In order to obtain the maximum performance from
the AAT3200 LDO regulator, careful consideration
should be given to the printed circuit board layout. If
grounding connections are not properly made,
power supply ripple rejection and LDO regulator
transient response can be compromised.
The LDO regulator external capacitors CIN and
COUT should be connected as directly as possible
to the ground pin of the LDO regulator. For maximum performance with the AAT3200, the ground
pin connection should then be made directly back
to the ground or common of the source power supply. If a direct ground return path is not possible
due to printed circuit board layout limitations, the
LDO ground pin should then be connected to the
common ground plane in the application layout.
PD(MAX) = (VIN - VOUT)IOUT + (VIN x IGND)
PD(150mA) = (4.2V - 3.0V)150mA + (4.2V x 20µA)
PD(150mA) = 180mW
