PRODUCT DATASHEET  
AAT3221/2  
PowerLinearTM  
150mA NanoPower™ LDO Linear Regulator  
The power dissipation for a 150mA load occurring for  
8.2% of the duty cycle will be 20.9mW. Finally, the two  
power dissipation levels can summed to determine the  
total true power dissipation under the varied load:  
Printed Circuit Board Layout  
Recommendations  
In order to obtain the maximum performance from the  
AAT3221/2 LDO regulator, very careful attention must  
be considered in regard to the printed circuit board lay-  
out. If grounding connections are not properly made,  
power supply ripple rejection and LDO regulator tran-  
sient response can be compromised.  
PD(total) = PD(100mA) + PD(150mA)  
PD(total) = 229.5mW + 30.75mW  
PD(total) = 260.25mW  
The LDO regulator external capacitors CIN and COUT  
should be connected as directly as possible to the ground  
pin of the LDO regulator. For maximum performance  
with the AAT3221/2, the ground pin connection should  
then be made directly back to the ground or common of  
the source power supply. If a direct ground return path  
is not possible due to printed circuit board layout limita-  
tions, the LDO ground pin should then be connected to  
the common ground plane in the application layout.  
The maximum power dissipation for the AAT3221/2  
operating at an ambient temperature of 85°C is 267mW.  
The device in this example will have a total power dis-  
sipation of 260.25mW. This is within the thermal limits  
for safe operation of the device.
