These ultra low dropout linear regulators respond fast to step changes in load which makes them suitable for low
voltage micro-processor applications. The TJ3964 is developed on a CMOS process technology which allows low
quiescent current operation independent of output load current. This CMOS process also allows the TJ3964 to
operate under extremely low dropout conditions.
