Description

The MIC49150 is a high-bandwidth, low-dropout, 1.5A voltage regulator ideal for powering core voltages of low power microprocessors. The MIC49150 implements a dual supply configuration allowing for very low output impedance and very fast transient response. The MIC49150 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 or proper operation. The MIC49150 offers fi xed output voltages from 0.9V to 1.8V and adjustable output voltages down to 0.9V. The MIC49150 requires a minimum of output capacitance for stability, working optimally with small ceramic capacitors. The MIC49150 is available in an 8-pin power MSOP package and a 5-pin S-Pak. Its operating temperature range is -40°C to +125°C.
