  The TJ49300 is a series of 3.0A high performance ultra low-dropout linear regulator ideal for powering core voltages of low-power microprocessors. 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 ultralow 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 from 0.8V to 1.8V and adjustable output voltages down to 0.8V. The TJ49300 is developed on a CMOS technology which allows low quiescent current operation independent of output current. This technology also allows the TJ49300 to operate under extremely low dropout conditions.
