Microchip | MIC2810-44MYML-TR

The MIC2810 is a high performance power management IC, integrating a 2 MHz DC/DC switcher with two 300 mA LDOs. The MIC2810 features a LOWQ ® mode, reducing the total current draw while in this mode to less than 30 µA. In LOWQ ® mode, the output noise of the DC/DC converter is 53 µVRMS , 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. It is available with fixed output voltages in a 16-pin 3 mm x 3 mm MLF ® leadless package.
