DESCRIPSION
The TJ3940 series of high performance ultra low-dropout linear regulators operates from 2.5V to 6V input supply
and provides ultra low-dropout voltage, high output current with low ground current. Wide range of preset output
voltage options are available. These ultra low dropout linear regulators respond fast to step changes in load which
makes them suitable for low voltage micro-processor applications. The TJ3940 is developed on a CMOS process
technology which allows low quiescent current operation independent of output load current. This CMOS process
also allows the TJ3940 to operate under extremely low dropout conditions.
