The LDO regulator output has been specifically

optimized to function with low cost, low equivalent

series resistance (ESR) ceramic capacitors.

However, the design will allow for operation with a

wide range of capacitor types.

Functional Description

The AAT3220 is intended for LDO regulator appli-

cations where output current load requirements

range from no load to 150mA.

The AAT3220 has complete short-circuit and ther-

mal protection. The integral combination of these

two internal protection circuits give the AAT3220 a

comprehensive safety system to guard against

extreme adverse operating conditions. Device

power dissipation is limited to the package type

and thermal dissipation properties. Refer to the

Thermal Considerations section of this datasheet

for details on device operation at maximum output

load levels.

The advanced circuit design of the AAT3220 has

been optimized for minimum quiescent or ground

current consumption, making it ideal for use in

power management systems for small battery-

operated devices. The typical quiescent current

level is just 1.1µA. The LDO also demonstrates

excellent power supply ripple rejection (PSRR) and

load and line transient response characteristics.

The AAT3220 is a truly high performance LDO reg-

ulator especially well suited for circuit applications

which are sensitive to load circuit power consump-

tion and extended battery life.
