US1206/1207/1208/1209 1A ULTRA LOW DROPOUT POSITIVE ADJUSTABLE & FIXED REGULATOR PRELIMINARY DATASHEET FEATURES DESCRIPTION Low Droput Voltage (500mV at 1A) 1% Voltage Reference Accuracy Low Ground Current 10uA Quiescent Current in Shutdown (US1207,1208) Fast Transient Response Current Limit and Thermal Shutdown Error Flag Signal for Output out of Regulation (US1207,1209) Pin Compatible with MIC39100/101/102 series APPLICATIONS 2.5V Supply from 3.3V Input for the new generation of Logic ICs Computer Mother Board, Add on Cards High Efficiency Post Regulator in SMPS The US1206 family of devices are ultra low dropout 1A regulators using PNP transistor as the pass element. These products are ideal when a single input supply is available only and the dropout voltage is less than 1V, exceeding the minimum dropout characteristics of NPN/ PNP hybrid regulators. One common application of these regulators are where input is 3.3V and a 2.5V output is needed. Besides the low dropout of less...
