General Description 
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
?/DIV>
 mode, reducing the total
current draw while in this mode to less than 30礎(chǔ). In
LOWQ
?/DIV>
 mode, the output noise of the DC to DC converter
is 75礦
RMS
, 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 礐ap design, operating with very small
ceramic output capacitors and inductors for stability,
reducing required board space and component cost and it
is available in fixed output voltages in the 16-pin
3mm x 3mm MLF
?/DIV>
 leadless package.
