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 1.1A. 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.
