θ
JA
(junction to air) is specified for the worst-case conditions,
that is, a device soldered in a circuit board for surface-mount
packages. The θ
JA
, θ
JB
(junction to board), and θ
JC
(junction to
case) are determined according to JESD51-9 on a 4-layer
printed circuit board (PCB) with natural convection cooling.
For the LFCSP package, the exposed pad must be soldered to
the GND1 and/or GND2 terminal(s) on the board.

The maximum operating junction temperature (T
J(MAX)
) supersedes the
maximum operating ambient temperature (T
A(MAX)
). See the Maximum
Temperature Ranges section for more information.
ESD CAUTION
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.
Absolute maximum ratings apply individually only, not in
combination. Unless otherwise specified, all voltages are
referenced to GND.
MAXIMUM TEMPERATURE RANGES
The maximum operating junction temperature (T
J(MAX)
)
supersedes the maximum operating ambient temperature
(T
A(MAX)
). Therefore, in situations where the ADP8860 is
exposed to poor thermal resistance and a high power
dissipation (P
D
), the maximum ambient temperature may need
to be derated. In these cases, the ambient temperature
maximum can be calculated with the following equation:
T
A(MAX)
= T
J(MAX)
