General Description
Features
The AAT3238 MicroPower low dropout (LDO) linear regulator is ideally suited for portable applications where
very fast transient response, extended battery life, and
small size are critical. The AAT3238 has been specifically
designed for high-speed turn-on and turn-off performance, fast transient response, good power supply ripple rejection (PSRR), and is reasonably low noise, making it ideal for powering sensitive circuits with fast
switching requirements.

Other features include low quiescent current, typically
70µA, and low dropout voltage, typically less than
400mV at the maximum output current level of 300mA.
The device is output short-circuit protected and has a
thermal shutdown circuit for additional protection under
extreme operating conditions.
The AAT3238 also features a low-power shutdown mode
for extended battery life. A reference bypass pin has
been provided to improve PSRR performance and output
noise by connecting a small external capacitor from the
AAT3238’s reference output to ground.
The AAT3238 is available in a Pb-free, space-saving
6-pin SOT23 or 8-pin SC70JW package in factory-programmed voltages.

Functional Description
The AAT3238 is intended for LDO regulator applications
where output current load requirements range from no
load to 300mA.
The advanced circuit design of the AAT3238 has been
specifically optimized for very fast start-up and shutdown timing. This proprietary CMOS LDO has also been
tailored for superior transient response characteristics.
These traits are particularly important for applications
that require fast power supply timing, such as GSM cellular telephone handsets.
The high-speed turn-on capability of the AAT3238 is
enabled through the implementation of a fast start control circuit, which accelerates the power-up behavior of
fundamental control and feedback circuits within the
LDO regulator.
Fast turn-off response time is achieved by an active output
pull-down circuit, which is enabled when the LDO regulator
is placed in the shutdown mode. This active fast shutdown
circuit has no adverse effect on normal device operation.
The AAT3238 has very fast transient response characteristics, which is an important feature for applications
where fast line and load transient response is required.
8
GND
This rapid transient response behavior is accomplished
through the implementation of an active error amplifier
feedback control. This proprietary circuit design is unique
to this MicroPower LDO regulator.
The LDO regulator output has been specifically optimized
to function with low-cost, low-ESR ceramic capacitors.
However, the design will allow for operation over a wide
range of capacitor types.
A bypass pin has been provided to allow the addition of
an optional voltage reference bypass capacitor to reduce
output self noise and increase power supply ripple rejection. Device self noise and PSRR will be improved by the
addition of a small ceramic capacitor in this pin. However,
increased values of CBYPASS may slow down the LDO regulator turn-on time.
This LDO regulator has complete short-circuit and thermal protection. The integral combination of these two
internal protection circuits gives the AAT3238 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 current loads.

300mA MicroPowerTM High Performance LDO Linear Regulator
Applications Information
To assure the maximum possible performance is obtained
from the AAT3238, 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
AAT3238 is physically located more than three centimeters from an 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 ESR
requirement for CIN. However, for 300mA 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 AAT3238 has been specifically designed to function
with very low ESR ceramic capacitors. For best performance, ceramic capacitors are recommended.
Typical output capacitor values for maximum output current conditions range from 1µF to 10µF. Applications
utilizing the exceptionally low output noise and optimum
power supply ripple rejection characteristics of the
AAT3238 should use 2.2µF or greater for COUT. If desired,
COUT may be increased without limit.
In low output current applications where output load is
less than 10mA, the minimum value for COUT can be as
low as 0.47µF.
3238.2008.05.1.7
Bypass Capacitor and
Low Noise Applications
A bypass capacitor pin is provided to enhance the low
noise characteristics of the AAT3238 LDO regulator. The
bypass capacitor is not necessary for operation of the
AAT3238. However, for best device performance, a small
ceramic capacitor should be placed between the bypass
pin (BYP) and the device ground pin (GND). The value of
CBYP may range from 470pF to 10nF. For lowest noise and
best possible power supply ripple rejection performance,
a 10nF capacitor should be used. To practically realize
the highest power supply ripple rejection and lowest
output noise performance, it is critical that the capacitor
connection between the BYP pin and GND pin be direct
and PCB traces should be as short as possible. Refer to
the PCB Layout Recommendations section of this document for examples.
There is a relationship between the bypass capacitor
value and the LDO regulator turn-on and turn-off time.
In applications where fast device turn-on and turn-off
time are desired, the value of CBYP should be reduced.
In applications where low noise performance and/or
ripple rejection are less of a concern, the bypass capacitor may be omitted. The fastest device turn-on time will
be realized when no bypass capacitor is used.
DC leakage on this pin can affect the LDO regulator output
noise and voltage regulation performance. For this reason,
the use of a low leakage, high quality ceramic (NPO or C0G
type) or film capacitor is highly recommended.
Capacitor Characteristics
Ceramic composition capacitors are highly recommended
over all other types of capacitors for use with the
AAT3238. 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 not prone to incorrect connection damage.
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, size and area, material composition, and ambient temperature. Typically, capacitor ESR

TM
300mA MicroPowerTM High Performance LDO Linear Regulator
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.
These two material types are not recommended for use
with LDO regulators since the capacitor tolerance can
vary more than ±50% over the operating temperature
range of the device. A 2.2µF Y5V capacitor could be
reduced to 1µF over temperature; this could cause problems for circuit operation. 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 an equivalent material and capacitance value. These larger devices can 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 LDO regulators.
conditions, the output of the LDO regulator will be current limited until the short-circuit condition is removed
from the output or the LDO regulator package power
dissipation exceeds the device thermal limit.
Thermal Protection
The AAT3238 has an internal thermal protection circuit
which will turn on when the device die temperature
exceeds 145°C. 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 145°C trip point.
The combination and interaction between the short-circuit and thermal protection systems allow the LDO regulator to withstand indefinite short-circuit conditions
without sustaining permanent damage.
No-Load Stability
The AAT3238 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.
Enable Function
Reverse Output-to-Input
Voltage Conditions and Protection
The AAT3238 features an LDO regulator enable/
disable function. This pin (EN) is active high and is compatible with CMOS logic. To assure the LDO regulator will
switch on, the EN turn-on control level must be greater
than 1.5V. The LDO regulator will go into the disable
shutdown mode when the voltage on the EN pin falls
below 0.6V. If the enable function is not needed in a
specific application, it may be tied to VIN to keep the LDO
regulator in a continuously on state.
Under normal operating conditions, a parasitic diode
exists between the output and input of the LDO regulator. The input voltage should always remain greater than
the output load voltage, maintaining a reverse bias on
the internal parasitic diode. Conditions where VOUT might
exceed VIN should be avoided since this would forward
bias the internal parasitic diode and allow excessive current flow into the VOUT pin, possibly damaging the LDO
regulator.
When the LDO regulator is in shutdown mode, an internal 1.5kΩ resistor is connected between VOUT and GND.
This is intended to discharge COUT when the LDO regulator is disabled. The internal 1.5kΩ has no adverse effect
on device turn-on time.
In applications where there is a possibility of VOUT
exceeding VIN for brief amounts of time during normal
operation, the use of a larger value CIN capacitor is
highly recommended. A larger value of CIN with respect
to COUT will effect a slower CIN decay rate during shutdown, thus preventing VOUT from exceeding VIN. In applications where there is a greater danger of VOUT exceeding VIN for extended periods of time, it is recommended
to place a Schottky diode across VIN to VOUT (connecting
the cathode to VIN and anode to VOUT). The Schottky
diode forward voltage should be less than 0.45V.
Short-Circuit Protection
The AAT3238 contains an internal short-circuit protection circuit that will trigger when the output load current
exceeds the internal threshold limit. Under short-circuit
