Microchip Technology MIC49300
The MIC49300 is a high-bandwidth, low-dropout, 3.0A voltage regulator ideal for powering core voltages of low-power microprocessors. The MIC49300 implements a dual supply configuration that allows for very low output impedance and very fast transient response. The MIC49300 requires a bias input supply and a main input supply, allowing for ultra-low input voltages on the main supply rail.| Part No. | MIC49300 |

GENERAL DESCRIPTION
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 offers fixed output voltages from 0.9V to 1.8V and adjustable output voltages down to 0.9V. The MIC49300 requires a minimum of output capacitance for stability, working optimally with small ceramic capacitors.
