DESCRIPSION
The TJ3965 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
μprocessor applications. The TJ3965 is developed on a
CMOS process technology which allows low quiescent
X.X = Output Voltage = 1.2, 1.8, 2.5, 3.3, and 5.0
current operation independent of output load current. This CMOS process also allows the TJ3965 to operate
under extremely low dropout conditions.
