turn-off time are desired, the value of C
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.

Considerations
For the best results, it is recommended to physi-
cally place the battery pack as close as possible to
the AAT2557 BAT pin. To minimize voltage drops
on the PCB, keep the high current carrying traces
adequately wide. The input capacitors should con-
nect as closely as possible to ADP and INLDO.
