Functional Description
The MIC2215 is a triple, low noise CMOS LDO.
Designed specifically for noise-critical applications in
handheld or battery-powered devices, the MIC2215
comes equipped with a noise reduction feature to filter
the output noise via an external capacitor. Other features
of the MIC2215 include a separate logic compatible
enable pin for each channel, current limit, thermal
shutdown, and ultra-fast transient response, all within a
small MLF
