Description

The AAT3223 PowerLinear NanoPower low dropout (LDO) linear regulator is ideal for portable applications where extended battery life is critical. This device features extremely low quiescent current which is typically 1.1µA. Dropout voltage is also very low, typically 190mV at 100mA. The AAT3223 has an enable pin feature which, when pulled low, will put the LDO regulator into shutdown mode, removing power from its load and offering extended power conservation capabilities for portable battery-powered applications. The AAT3223 also has a Power-OK (POK) feature. The POK function monitors the LDO output voltage and will alert the system if the output falls out of regulation.

The AAT3223 has output short-circuit and overcurrent protection. In addition, the device has an over-temperature protection circuit, which will shut down the LDO regulator during extended over-current events.

The AAT3223 is available in a space-saving 6-pin SOT23 package and is rated over the -40°C to +85°C temperature range.

The AAT3223 is similar to the AAT3221 with the exception that it offers the additional Power-OK function through the POK pin.
