The AAT3201 PowerLinear OmniPower low dropout(LDO) linear regulator is ideal for systems where alow-cost solution is critical. This device featuresextremely low quiescent current, typically 20μA.Dropout voltage is also very low, typically 200mV.The AAT3201 has an enable pin feature which,when pulled low, will enter the LDO regulator intoshutdown mode, removing power from its load andoffering extended power conservation capabilitiesfor portable, battery-powered applications.
