The MIC59300-1.2YME is a high-bandwidth, low-dropout, 3A linear voltage regulator ideal for powering core voltages of low-power microprocessors. The MIC59300-1.2YME implements a dual supply configuration allowing for a very low output impedance and a very fast transient response.
The MIC59300-1.2YME requires a bias input supply and a main input supply, allowing for ultra-low input voltages on the main supply rail. The device operates from an input supply of 1.0V to 3.8V and bias supply between 3V and 5.5V. The MIC59300-1.2YME offers fixed output voltages and adjustable output voltages down to 0.5V.
The MIC59300-1.2YME requires a minimum output capacitance for stability, working optimally with small ceramic capacitors.
The MIC59300-1.2YME is available in a 5-pin TO-263 and an 8-pin ePad SOIC package and its junction temperature range is -40°C to +125°C.
