Features & Applications
The MIC49150WR TR is a high-bandwidth, low-dropout, 1.5 A 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 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.
