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.
