Ultra-Low-Noise Application
MIC5206
Thermal Considerations
Layout
The MIC5206-x.xBM5 (5-pin SOT-23 package) has the
following thermal characteristics when mounted on a
single layer copper-clad printed circuit board.
Multilayer boards having a ground plane, wide traces
near the pads, and large supply bus lines provide better
thermal conductivity.

required. The error flag is shown with a 47k ? pull-up
resistor.
Adjustable Regulator Applications
Figure 3 shows the MIC5206BMM adjustable output
voltage configuration. Two resistors set the output
voltage. The formula for output voltage is:
SOT-23-5 Thermal Characteristics
The “worst case” value of 220°C/W assumes no ground
plane, minimum trace widths, and a FR4 material board.
The MIC5206-xxBMM (8-pin MSOP) has a thermal
resistance of 200°C/W when mounted on a FR4 board
with minimum trace widths and no ground plane.

Resistor values are not critical because ADJ (adjust) has
a high input impedance, but for best results use resistors

of 470k ? or less. A capacitor from ADJ to ground
provides greatly improved noise performance.
MSOP Thermal Characteristics
Nominal Power Dissipation and Die Temperature
The MIC5206-x.xBM5 at a 25°C ambient temperature
will operate reliably at over 450mW power dissipation
when mounted in the “worst case” manner described
above. At an ambient temperature of 40°C, the device
may safely dissipate over 380mW. These power levels
are equivalent to a die temperature of 125°C, the
maximum operating junction temperature for the
MIC5206.

Sink Area For Surface Mount Packages”.

Figure 3 also includes a 470pF capacitor for lowest-
noise operation and shows EN (pin 7) connected to IN
(pin 8) for an application where enable/shutdown is not
required. C OUT = 2.2μF minimum. The error flag is shown
with a 47k ? pull-up resistor.
