Product Summary
The MIC49300-1.2WR is a high-bandwidth, low-dropout, 3.0A voltage regulator ideal for powering core voltages of low-power microprocessors. The MIC49300-1.2WR implements a dual supply confi guration allowing for very low output impedance and very fast transient response. The MIC49300-1.2WR requires a bias input supply and a main input supply, allowing for ultra-low input voltages on the main supply rail. The input supply operates from 1.4V to 6.5V and the bias supply requires between 3V and 6.5V for proper operation. The MIC49300-1.2WR offers fi xed output voltages from 0.9V to 1.8V and adjustable output voltages down to 0.9V.
