DESCRIPTION
One common application of these regulators is where input is 3.3V and a 2.5V output is needed. Besides the low dropout of less than 0.5V, other features of the family of the parts are: micro-power shutdown capability and output UVLO detection where Flag pin is switched low when output is below 5% of its nominal point. FEATURES
Low Dropout Voltage (500mV at 1A) 1% Voltage Reference Accuracy Low Ground Current 1µA Maximum Quiescent Current in Shutdown (APU1207, APU1208) Fast Transient Response Current Limit and Thermal Shutdown Error Flag Signal for Output out of Regulation (APU1207, APU1208) RoHS Compliant APPLICATIONS
