Applications with Backup Power Tiny 16-Pin 3mm x 3mm QFN Package The MIC2800 is a high-performance power
management IC, featuring three output voltages with
maximum efficiency. Integrating a 2 MHz DC/DC
converter with an LDO post-regulator, the MIC2800
gives two high-efficiency outputs with a second,
300 mA LDO for maximum flexibility. The MIC2800
features a LOWQ mode, reducing the total current …
