DESCRIPSION
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 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.
