AAT3220
150mA NanoPowerTM LDO Linear Regulator
General Description
Features
The AAT3220 PowerLinear NanoPower low dropout (LDO)
linear regulator is ideal for portable applications where
extended battery life is critical. This device features
extremely low quiescent current, typically 1.1µA. Dropout
voltage is also very low, typically less than 225mV at the
maximum output current of 150mA. The AAT3220 has
output short-circuit and over-current protection. In addition, the device also has an over-temperature protection
circuit which will shut down the LDO regulator during
extended over-current events.

The AAT3220 is available in a Pb-free, space-saving
SC59 package. The device is rated over the -40°C to
+85°C temperature range. Since only a small, 1µF
ceramic output capacitor is required, often the only
space used is that occupied by the AAT3220 itself. The
AAT3220 is truly a compact and cost-effective voltage
conversion solution.
The AAT3221/2 are similar products for this application,
especially when a shutdown mode is required for further
power savings.

Functional Description
The AAT3220 is intended for LDO regulator applications
where output current load requirements range from no
load to 150mA.
The advanced circuit design of the AAT3220 has been
optimized for minimum quiescent or ground current consumption, making it ideal for use in power management
systems for small battery-operated devices. The typical
quiescent current level is just 1.1µA. The LDO also demonstrates excellent power supply ripple rejection (PSRR)
and load and line transient response characteristics. The
AAT3220 is a truly high performance LDO regulator
especially well suited for circuit applications which are
sensitive to load circuit power consumption and extended battery life.
8
The LDO regulator output has been specifically optimized
to function with low cost, low equivalent series resistance
(ESR) ceramic capacitors. However, the design will allow
for operation with a wide range of capacitor types.
The AAT3220 has complete short-circuit and thermal
protection. The integral combination of these two internal protection circuits give the AAT3220 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.

DATA SHEET
AAT3220
150mA NanoPowerTM LDO Linear Regulator
Applications Information
To assure the maximum possible performance is obtained
from the AAT3220, 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 AAT3220
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 close 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
ESR requirement for CIN. For 150mA 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 as direct as practically possible for
maximum device performance. The AAT3220 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 very
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 AAT3220 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
AAT3220. 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

DATA SHEET
AAT3220
150mA NanoPowerTM LDO Linear Regulator
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,
which 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 AAT3220 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’s 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 AAT3220’s 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 120°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 AAT3220 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.
10
Thermal Considerations and
High Output Current Applications
The AAT3220 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.
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 AAT3220 are TJ(MAX), the maximum
junction temperature for the device which is 125°C and
QJA = 200°C/W, the package 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 AAT3220
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 would
increase. If the condition remained constant and the
short-circuit protection did not activate, there would be a
potential damage hazard to the LDO regulator since the
thermal protection circuit will only activate after a shortcircuit event occurs on the LDO regulator output.

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.
plish 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.
PD(MAX) = (VIN - VOUT)IOUT + (VIN ⋅ IGND)
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:
This formula can be solved for VIN to determine the
maximum input voltage.
VIN(MAX) =
PD(MAX) + (VOUT ∙ IOUT)
IOUT + IGND
The following is an example for an AAT3220 set for a
3.0V output:
IGND
= 1.1µA
VOUT
= 3.0V
IOUT
= 150mA
IOUT
= 150mA
VIN
= 5.0V
IGND
= 1.1µA
VOUT = 3.0V
VIN(MAX) =
500mW + (3.0V ∙ 150mA)
150mA + 1.1µA
VIN(MAX) = 6.33V
From the discussion above, PD(MAX) was determined to
equal 500mW at TA = 25°C.
Thus, the AAT3220 can sustain a constant 3.0V output
at a 150mA load current as long as VIN is ≤ 6.33V at an
ambient temperature of 25°C. 5.5V is the maximum
input operating voltage for the AAT3220, thus at 25°C,
the device would not have any thermal concerns or
operational VIN(MAX) limits.
%DC =
%DC =
PD(MAX)
(VIN - VOUT) ∙ IOUT + (VIN ∙ IGND)
200mW
(5.0V - 3.0V) ∙ 150mA + (5.0V ∙ 1.1µA)
%DC = 66.67%
PD(MAX) is assumed to be 200mW.
For a 150mA output current and a 2.0V drop across the
AAT3220 at an ambient temperature of 85°C, the maximum on-time duty cycle for the device would be
66.67%.
This situation can be different at 85°C. The following is an
example for an AAT3220 set for a 3.0V output at 85°C:
VOUT
= 3.0V
IOUT
= 150mA
IGND
= 1.1µA
VIN(MAX) =
200mW + (3.0V ∙ 150mA)

VIN(MAX) = 4.33V
From the discussion above, PD(MAX) was determined to
equal 200mW at TA = 85°C.
Higher input-to-output voltage differentials can be
obtained with the AAT3220 while maintaining device

High Peak Output Current Applications
Some applications require the LDO regulator to operate
at continuous nominal levels with short duration, highcurrent peaks. The duty cycles for both output current
levels must be taken into account. To do so, first 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 AAT3220IGY-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 4.2V.
First, the current duty cycle percentage must be calculated:
Duty Cycle (%)
Device Duty Cycle vs. VDROP
% Peak Duty Cycle: X/100 = 378µs/4.61ms
% Peak Duty Cycle = 8.2%
(VOUT = 3.0V @ 50°C)

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.

The power dissipation for 100mA load occurring for

PD(150mA) = 180mW
PD(8.2%D/C) = %DC · PD(150mA)
PD(8.2%D/C) = 0.082 · 180mW
PD(8.2%D/C) = 14.8mW

DATA SHEET
AAT3220
150mA NanoPowerTM LDO Linear Regulator
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 AAT3220 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
AAT3220 LDO regulator, very careful attention must be
paid in regard 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 AAT3220, 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.
