The TJ49300 implements a dual supply configuration allowing for very low output impedance. The TJ49300 requires a bias input supply and a main input supply, allowing for very low input voltages on the main supply rail. The input supply operates from 1.4V to 5.5V and the bias supply requires between 3V and 5.5V for proper operation. The TJ49300 offers fixed output voltages 1.0V and 1.2V and adjustable output voltages down to 0.8V. The TJ49300 is developed on a CMOS technology that allows low quiescent current operation independent of output current. This technology also allows the TJ49300 to operate under extremely low dropout conditions.
