The MIC2810 is a high performance power management IC, integrating a 2MHz DC/DC switcher with two 300mA LDOs. The MIC2810 features a LowQ® mode, reducing the total current draw while in this mode to less than 30µA. In LowQ®mode, the output noise of the DC/DC converter is 53µVrms , significantly lower than other converters that use a PFM light load mode that can interfere with sensitive RF circuitry.The MIC2810 is a µCap design, operating with very small ceramic output capacitors and inductors for stability, therefore, reducing required board space and component cost.
