UNISEM US1206

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. The US1206-XX in SOT223 is pin compatible with MIC39100-XX, US1207 and 1209 in SO8 power package are compatible with MIC39101 and 39102 respectively.

FEATURES

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

DESCRIPTION

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 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.
