Accuracy when VOUT is connected directly to ADJ. When the VOUT voltage is set by external feedback resistors, the absolute accuracy in adjust mode depends on the
tolerances of resistors used.
2
Based on an end-point calculation using 0 μA and 150 mA loads.
3
Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage. This applies only for output
voltages above 2.2 V.
4
Start-up time is defined as the time between the rising edge of EN to V
OUT
being at 90% of its nominal value.
5
Current limit threshold is defined as the current at which the output voltage drops to 90% of the specified typical value. For example, the current limit for a 3.0 V
output voltage is defined as the current that causes the output voltage to drop to 90% of 3.0 V or 2.7 V.

The minimum input and output capacitance should be greater than 0.7 µF over the full range of operating conditions. The full range of operating conditions in the
application must be considered during device selection to ensure that the minimum capacitance specification is met. X7R and X5R type capacitors are recommended;
however, Y5V and Z5U capacitors are not recommended for use with any LDO.

ADP160/ADP161/ADP162/ADP163
Junction-to-ambient thermal resistance (θ
JA
) of the package is
based on modeling and calculation using a 4-layer board. The
junction-to-ambient thermal resistance is highly dependent on the
application and board layout. In applications where high maximum
power dissipation exists, close attention to thermal board design
is required. The value of θ
JA
may vary, depending on PCB material,
layout, and environmental conditions. The specified values of
θ
JA
are based on a 4-layer, 4 inches × 3 inches, circuit board. Refer
to JESD 51-7 and JESD 51-9 for detailed information on the
board construction. For additional information, see the
AN-617
Application Note,
MicroCSP™ Wafer Level Chip Scale Package.
Ψ
JB
is the junction to board thermal characterization parameter
with units of °C/W. Ψ
JB
of the package is based on modeling and
calculation using a 4-layer board. The JESD51-12,
Guidelines for
Reporting and Using Electronic Package Thermal Information,
states that thermal characterization parameters are not the same
as thermal resistances. Ψ
JB
measures the component power flowing
through multiple thermal paths rather than a single path as in
thermal resistance, θ
JB
. Therefore, Ψ
JB
thermal paths include
convection from the top of the package as well as radiation from
the package, factors that make Ψ
JB
more useful in real-world
applications. Maximum junction temperature (T
J
) is calculated
from the board temperature (T
B
) and power dissipation (P
D
)
using the formula
T
J
=
T
B
+ (P
D
× Ψ
JB
)
Refer to JESD51-8 and JESD51-12 for more detailed information
about Ψ
JB
.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
THERMAL DATA
Absolute maximum ratings only apply individually; they do not
apply in combination. The
ADP16x
can be damaged when the
junction temperature limits are exceeded. Monitoring ambient
temperature does not guarantee that T
J
is within the specified
temperature limits. In applications with high power dissipation
and poor thermal resistance, the maximum ambient temperature
may have to be derated.
In applications with moderate power dissipation and low PCB
thermal resistance, the maximum ambient temperature can
exceed the maximum limit as long as the junction temperature
is within specification limits. The junction temperature (T
J
) of
the device is dependent on the ambient temperature (T
A
), the
power dissipation of the device (P
D
), and the junction-to-ambient
thermal resistance of the package (θ
JA
).
Maximum junction temperature (T
J
) is calculated from the ambient
temperature (T
A
) and power dissipation (P
D
) using the formula
T
J
=
T
A
+ (P
D

THERMAL RESISTANCE
θ
JA
and Ψ
JB
are specified for the worst-case conditions, that is, a
device soldered in a circuit board for surface-mount packages.
