DESCRIPSION

The TJ3964 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.

X.X = Output Voltage = 1.2, 1.5, 1.8, 2.5, and 3.3

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.
