DESCRIPSION
The TJ49150 is a series of 1.5A high performance ultra
low dropout linear regulator ideal for powering core
voltages of low-power microprocessors. The
TJ49150 implements a dual supply configuration
allowing for very low output impedance. The
TJ49150 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 TJ49150 offers
adjustable output voltages down to 0.8V. The
TJ49150 is developed on a CMOS technology which
allows low quiescent current operation independent
of output current. This technology also allows the
TJ49150 to operate under extremely low dropout
conditions.
