MIC49200
The heat sink may be signi
fi
cantly reduced in
applications where the maximum input voltage is
known and large compared with the dropout voltage.
Use a series input resistor to drop excessive voltage
and distribute the heat between this resistor and the
regulator.
The
low-dropout
MIC49200 allow signi
fi
cant reductions in regulator
power dissipation and the associated heat sink
without compromising performance. When this
technique is employed, a capacitor of at least 1μF is
needed directly between the input and regulator
ground. Refer to “
Application Note 9
” for further details
and examples on thermal design and heat sink
speci
fi
cation.

properties
of
the
Minimum Load Current
The MIC49200, unlike most other high current
regulators, does not require a minimum load to
maintain output voltage regulation.
Adjustable Regulator Design
The
MIC49200
programming the output voltage anywhere between
0.9V and 5V. Two resistors are used. The resistor
value between V
OUT
and the adjust pin should not
exceed 10k
. Larger values can cause instability. The
resistor values are calculated by:

Enable
The
fi
xed output voltage versions of the MIC49200
feature an active high enable input (EN) that allows
on-off control of the regulator. Supply currents reduce
to “zero” when the device is in shutdown, with only
microamperes of leakage current. The EN input has
TTL/CMOS compatible thresholds for simple logic
interfacing. EN may be directly tied to V
IN
and pulled
up to the maximum supply voltage.
