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.
