AAT3220  
150mA NanoPower™ LDO Linear Regulator  
PowerLinear  
General Description  
Features  
The AAT3220 PowerLinear NanoPower low  
dropout (LDO) linear regulator is ideal for portable  
applications where extended battery life is critical.  
This device features extremely low quiescent cur-  
rent, typically 1.1µA. Dropout voltage is also very  
low, typically less than 225mV at the maximum out-  
put current of 150mA. The AAT3220 has output  
short-circuit and over-current protection. In addi-  
tion, the device also has an over-temperature pro-  
tection circuit which will shut down the LDO regu-  
lator during extended over-current events.  
1.1µA Quiescent Current  
Low Dropout: 200mV (typ)  
Guaranteed 150mA Output  
High Accuracy: ±2.0%  
Current Limit and Over-Temperature  
Protection  
Low Temperature Coefficient  
Factory-Programmed Output Voltages:  
1.8V to 3.5V  
Stable Operation With Virtually Any Output  
Capacitor Type  
3-Pin SOT-89 or SC59 Package  
4kV ESD Rating  
The AAT3220 is available in a Pb-free, space-saving  
SC59 package, or a Pb-free SOT-89 package for  
applications requiring increased power dissipation.  
The device is rated over the -40°C to +85°C tem-  
perature range. Since only a small, 1µF ceramic  
output capacitor is required, often the only space  
used is that occupied by the AAT3220 itself. The  
AAT3220 is truly a compact and cost-effective volt-  
age conversion solution.  
Applications  
Cellular Phones  
Digital Cameras  
Handheld Electronics  
Notebook Computers  
PDAs  
Portable Communication Devices  
Remote Controls  
The AAT3221/2 is a similar product for this appli-  
cation, especially when a shutdown mode is  
required for further power savings.
