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.

FEATURES
