AAT3200
OmniPowerTM 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 overcurrent events.
• 150mA Output
• 20µA Quiescent Current
• Low Dropout: 200mV (typical)
• High Accuracy: ±2.0%
• Current Limit Protection
• Over-Temperature Protection
• Low Temperature Coefficient
• Factory-Programmed Output Voltages: 2.0V to 3.5V
• Stable Operation With Virtually Any Output Capacitor
Type
• 3-Pin SC59 Package
The AAT3200 is available in a space-saving, Pb-free SC59
package. 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.
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.
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
8
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.
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

AAT3200
OmniPowerTM LDO Linear Regulator
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.
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:
DI = maximum step in output current
DV= 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 nonpolarized. 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 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 lowcost 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.

DATA SHEET
AAT3200
OmniPowerTM LDO Linear Regulator
Short-Circuit and Thermal Protection
The AAT3200 is protected by both current limit and overtemperature 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 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 short-circuit 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 no-load 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 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.
10
At any given ambient temperature (TA), the maximum
package power dissipation can be determined by the following equation:
PD(MAX) =
TJ(MAX) - TA
ΘJA
Constants for the AAT3200 are TJ(MAX), the maximum
junction temperature for the device (125°C) and QJA =
200°C/W, the 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
This formula can be solved for VIN to determine the
maximum input voltage.
VIN(MAX) =
PD(MAX) + VOUT ∙ IOUT
IOUT + IGND

AAT3200
OmniPowerTM LDO Linear Regulator
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.
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:
VOUT
= 3.0V
IOUT
= 150mA
IGND
= 20µA
IGND
= 20µA
IOUT
= 150mA
VIN
= 5.0V
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
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.
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
PD(MAX) is assumed to be 200mW.
VOUT = 3.0V
%DC =
PD(MAX)
(VIN - VOUT) ∙ IOUT + VIN ∙ IGND
%DC =
200mW
(5.0V - 3.0V) ∙ 150mA + 5.0V ∙ 20µA
%DC = 66.6%
For a 150mA output current and a 2.0V drop across the
AAT3200 at an ambient temperature of 85°C, the maximum on-time duty cycle for the device would be 66.6%.
The following family of curves shows the safe operating
area for duty-cycled operation from ambient room temperature to the maximum operating level.
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 AAT3200IGY-3.0-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(100mA) = (4.2V - 3.0V) · 100mA + 4.2V · 20µA
PD(100mA) = 120mW
PD(91.8%D/C) = %DC · PD(100mA)
PD(91.8%D/C) = 0.918 · 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(MAX) = (VIN - VOUT)IOUT + VIN · IGND
PD(150mA) = (4.2V - 3.0V) · 150mA + 4.2V · 20µA
PD(150mA) = 180mW
PD(8.2%D/C) = %DC · PD(150mA)
PD(8.2%D/C) = 0.082 · 180mW
PD(8.2%D/C) = 14.8m
12
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.
