AAT3220
150mA NanoPower™ LDO Linear Regulator
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.
