General Description
The AME8830 is designed for portable and wireless
application with low dropout voltage and optimized perfor-
mance for battery powered systems to deliver ultra low
noise. The space-saving SOT-25 package is attractive for
Pocket and Hand Held applications.
The AME8830 is stable with a small 1uF output ca-
pacitor.
In applications requiring a low noise without slowing
down the load transient response, Place a 0.01uF ca-
pacitor between Bypass and Ground.
