The power dissipated by the LDO for given application
conditions can be calculated by the next equation:

(eq. 2)
Where I
GND
is the LDO’s ground current, dependent on
the output load current.
Connecting the exposed pad and
N/C pin to a large ground
planes helps to dissipate the heat from the chip.
The relation of θ
JA
and P
D(MAX)
to PCB copper area and
Cu layer thickness could be seen on the Figure 30.
Reverse Current
The PMOS pass transistor has an inherent body diode
which will be forward biased in the case when V
OUT
> V
IN
.
Due to this fact in cases, where the extended reverse current
condition can be anticipated the device may require
additional external protection.
Power Supply Rejection Ratio
The LDO features very high power supply rejection ratio.
The PSRR at higher frequencies (in the range above
100 kHz) can be tuned by the selection of C
OUT
capacitor
and proper PCB layout. A simple LC filter could be added
to the LDO’s IN pin for further PSRR improvement.
Enable Turn−On Time
The enable turn−on time is defined as the time from EN
assertion to the point in which V
OUT
will reach 98% of its
nominal value. This time is dependent on various
application conditions such as V
OUT−NOM
, C
OUT
and T
A
.
PCB Layout Recommendations
To obtain good transient performance and good regulation
characteristics place C
IN
and C
OUT
capacitors as close as
possible to the device pins and make the PCB traces wide.
In order to minimize the solution size, use 0402 or 0201
capacitors size with appropriate effective capacitance.
Larger copper area connected to the pins will also improve
the device thermal resistance. The actual power dissipation
can be calculated from the equation above (Power
Dissipation section). Exposed pad and N/C pin should be
tied to the ground plane for good power dissipation.
