PRELIMINARY DATASHEET

FEATURES

DESCRIPTION

Low Droput Voltage (500mV at 1A)

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

(US1207,1209)

Besides the low dropout of less than 0.5V, other fea-

Pin Compatible with MIC39100/101/102 series

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.

APPLICATIONS
