General Description

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.
