MIC2800-G2SYML-TR

16VQFN 3x3x0.90mmcse5000M

DC-DC + 2 Linear Regulators with LowQ Mode & POR

The MIC2800 is a high performance power management IC, giving three output voltages with maximum efficiency. Integrating a 2MHz DC/DC converter with an LDO post regulator, the MIC2800 gives two high efficiency outputs with a second, 300mA LDO for maximum flexibility. The MIC2800 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 to DC converter is 75µVRMS, significantly lower than other converters which use a PFM light load mode that can interfere with sensitive RF circuitry.The DC to DC converter uses small values of L and C to reduce board space but still retains efficiencies over 90% at load currents up to 600mA.The MIC2800 is a μCap design, operating with very small ceramic output capacitors and inductors for stability, reducing required board space and component cost.
