1 / 16 page  AAT3220 150mA NanoPower™ LDO Linear Regulator 3220.2006.01.1.4 1 PowerLinear™ General Description 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. 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. The AAT3221/2 is a similar product for this appli- cation, especially when a shutdown mode is required for further power savings.
