DESCRIPTION
The TJ4230 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 TJ4230 is developed on a CMOS process
technology which allows low quiescent current operation
independent of output load current. This CMOS process
also allows the TJ4230 to operate under extremely low
dropout conditions.
