AAT3221/2  
150mA NanoPower™ LDO Linear Regulator  
PowerLinear  
General Description  
Features  
The AAT3221 and AAT3222 PowerLinear  
NanoPower low dropout (LDO) linear regulators  
are ideal for portable applications where extended  
battery life is critical. These devices feature  
extremely low quiescent current, typically 1.1µA.  
Dropout voltage is also very low, typically less than  
200mV at the maximum output current of 150mA.  
The AAT3221/2 have an enable pin feature which,  
when asserted, will enter the LDO regulator into  
shutdown mode, removing power from its load and  
offering extended power conservation capabilities  
for portable battery-powered applications.  
1.1µA Quiescent Current  
Low Dropout: 200mV (typical)  
Guaranteed 150mA Output  
High Accuracy: ±2%  
Current Limit Protection  
Over-Temperature Protection  
Extremely Low Power Shutdown Mode  
Low Temperature Coefficient  
Factory-Programmed Output Voltages  
— 1.6V to 3.5V  
Stable Operation With Virtually Any Output  
Capacitor Type  
Active High or Low Enable Pin  
4kV ESD  
5-Pin SOT23 or 8-Pin SC70JW Package  
-40°C to +85°C Temperature Range  
The AAT3221/2 have output short-circuit and over-  
current protection. In addition, the devices also  
have an over-temperature protection circuit, which  
will shut down the LDO regulator during extended  
over-current events. The devices are available  
with active high or active low enable input.  
The AAT3221 and AAT3222 are available in Pb-free,  
space-saving 5-pin SOT23 packages. The AAT3221  
is also available in a Pb-free, 8-pin SC70JW pack-  
age. The device is rated over the -40°C to +85°C  
temperature range. Since only a small, 1µF ceram-  
ic output capacitor is recommended, often the only  
space used is that occupied by the AAT3221/2 itself.  
The AAT3221/2 provide a compact and cost-effec-  
tive voltage conversion solution.  
Applications  
Cellular Phones  
Digital Cameras  
Handheld Electronics  
Notebook Computers  
PDAs  
Portable Communication Devices  
Remote Controls  
The AAT3221 and AAT3122 are similar to the  
AAT3220, with the exception that they offer further  
power savings with an enable pin.
