PRODUCT DATASHEET  
AAT3221/2  
PowerLinearTM  
150mA NanoPower™ LDO Linear Regulator  
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, typi-  
cally 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 offer-  
ing 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  
▪ 1.5V to 3.5V  
• Stable Operation With Virtually Any Output Capacitor  
Type  
• Active High or Low Enable Pin  
• 4kV ESD  
The AAT3221/2 have output short-circuit and over-cur-  
rent 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.  
• 5-Pin SOT23 or 8-Pin SC70JW Package  
• -40°C to +85°C Temperature Range  
Applications  
• Cellular Phones  
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 package. The  
device is rated over the -40°C to +85°C temperature  
range. Since only a small, 1μF ceramic output capacitor  
is recommended, often the only space used is that occu-  
pied by the AAT3221/2 itself. The AAT3221/2 provide a  
compact and cost-effective voltage conversion solution.  
• 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.
