AAT3223IGU-2.8-T1中文资料台湾类比科技数据手册PDF规格书

General 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, typically 1.1µA. Dropout voltage is also very low, typically 190mV at 100mA. The AAT3223 has an enable pin 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 PowerOK (POK) feature which monitors the LDO output voltage and will alert the system if the output falls out of regulation.
