Functional Description

The AAT3221 and AAT3222 are intended for LDO

regulator applications where output current load

requirements range from no load to 150mA. The

advanced circuit design of the AAT3221/2 has been

optimized for very low quiescent or ground current

consumption, making it ideal for use in power man-

agement systems for small battery-operated

devices. The typical quiescent current level is just

1.1µA. AAT3221/2 devices also contain an enable

circuit which has been provided to shut down the

LDO regulator for additional power conservation in

portable products. In the shutdown state, the LDO

draws less than 1µA from input supply.

tery life.

The LDO regulator output has been specifically

optimized to function with low-cost, low-ESR

ceramic capacitors. However, the design will allow

for operation with a wide range of capacitor types.

The AAT3221/2 has complete short-circuit and

thermal protection. The integral combination of

these two internal protection circuits gives the

AAT3221/2 a comprehensive safety system to

guard against extreme adverse operating condi-

tions. Device power dissipation is limited to the

package type and thermal dissipation properties.

Refer to the Thermal Considerations section of this

document for details on device operation at maxi-

mum output load levels.

The LDO also demonstrates excellent power sup-

ply ripple rejection (PSRR) and load and line tran-

sient response characteristics. The AAT3221/2
