TYPICAL APPLICATION
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 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 fea-
tures 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 compatible with
MIC39100-XX, US1207 and 1209 in SO8 power package
are compatible with MIC39101 and 39102 respectively.
