LDO Regulator for Portable Systems  
turn-off time are desired, the value of CBYP should  
be reduced.  
Printed Circuit Board Layout  
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.  
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.
