US1206
FEATURES
Low Droput Voltage (500m V at 1A) 1% Voltage Reference Accuracy Low Ground Current 10u A 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 patible with MIC39100/101/102 series
DESCRIPTION
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 mon application of these regulators are 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; micropower shutdown capability and output UVLO detection where Flag pin is switched low when output is below 5% of its nominal point. The US1206-XX in SOT223 is pin patible with MIC39100-XX, US1207 and 1209...
