The MIC47300 is a high-bandwidth, low-dropout, 3A voltage regulator that is ideal for powering core voltages of low-power microprocessors. The MIC47300 implements a dual supply conï¬ guration allowing for very low output impedance and very fast transient response. The MIC47300 requires a bias input supply between 3V and 6.5V for proper operation. The main input supply rail operates from 1.4V to 6.5V and allows for adjustable output voltages down to 0.9V. The MIC47300 requires a minimum of 1µF output capacitance for stability, and optimal operation is achieved with small ceramic capacitors. The MIC47300 is available in a 5-pin power D-Pak package (TO-252) with an operating temperature range of -40°C to +125°C.
