DESCRIPTION
SOP8
The TJ5631 of two channels high performance ultra-low
dropout linear regulators operates from 2.5V to 5.5V input
supply and provides ultra-low dropout voltage with low
ground current. These ultra-low dropout linear regulators
respond fast to step changes in load which makes them
suitable for low voltage micro-processor applications. The
TJ5631 is developed on a CMOS process technology which
allows low quiescent current operation independent of
output load current. This CMOS process also allows the
TJ5631 to operate under extremely low dropout conditions.
