CAT3200/3200-5  
APPLICATION INFORMATION  
Ceramic Capacitors  
Ceramic capacitors of different dielectric materials lose  
theircapacitancewithhighertemperatureandvoltageat  
different rates. For example, a capacitor made of X5R or  
X7R material will retain most of its capacitance from –  
40°C to 85°C whereas a Z5U or Y5V style capacitor will  
lose considerable capacitance over that range.  
The overall junction to ambient thermal resistance (θJA)  
for device power dissipation (PD) consists primarily of  
two paths in series. The first path is the junction to the  
case (θJC) which is defined by the package style, and the  
second path is case to ambient (θCA) thermal resistance  
which is dependent on board layout. The final operating  
junction temperature for any set of conditions can be  
estimated by the following thermal equation:  
TJUNC = TAMB + P (ΘJC ) + P (ΘCA )  
D

Z5UandY5Vcapacitorsmayalsohavevoltagecoefficient  
causing them to lose 60% or more of their capacitance  
when the rated voltage is applied. When comparing  
differentcapacitorsitisoftenusefulconsidertheamount  
of achievable capacitance for a given case size rather  
than discussing the specified capacitance value. For  
example,overratedvoltageandtemperatureconditions,  
a 1µF, 10V, Y5V ceramic capacitor in an 0603 case may  
not provide any more capacitance than a 0.22µF, 10V,  
X7R available in the same 0603 case. For many  
CAT3200/CAT3200-5applicationsthesecapacitorscan  
be considered roughly equivalent.  
= TAMB + P (ΘJA )  
D
The CAT3200 in SOT23 package, when mounted on  
printed circuit board with two square inches of copper  
allocated for “heat spreading”, will result with an overall  
θJA of less than 150°C/W.  
For a typical application operating from a 3.8V input  
supply, the maximum power dissipation is 260mW  
(100mA x 3V). This would result if a maximum junction  
temperature of :  
The capacitor manufacturer’s data sheet should be  
consultedtodeterminewhatvalueofcapacitorisneeded  
to ensure the desired capacitance at all temperatures  
and voltages. Below is a list of ceramic capacitor  
manufacturers and how to contact them:

JUNC = TAMB + P (θJA)  
D
= 85°C + 0.26W (150°C/W)  
= 85°C + 39°C = 124°C  
The use of multi-layer board construction with power  
planes will further enhance the overall thermal  
performance. In the event of no dedicated copper area  
being used for heat spreading, a multi-layer board will  
typically provide the CAT3200 with an overall θJA of  
200°C/W. This level of thermal conduction would allow  
up to 200mW be safely dissipated within the device.

Thermal Management  
For higher input voltages and maximum output current  
there can be substantial power dissipation in the  
CAT3200/CAT3200-5. If the junction temperature  
increases to 160°C, the thermal shutdown circuitry will  
automatically turn off the output.  
A good thermal connection to the PC board is  
recommended to reduce the chip temperature.  
ConnectingtheGNDpin(Pins4/5forCAT3200,Pin2for  
CAT3200-5) to a ground plane, and maintaining a solid  
ground plane under the device reduces the overall  
thermal resistance.
