The APU1209 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 only available and the dropout voltage is less than 1V, exceeding the minimum dropout characteristics of NPN/ PNP hybrid regulators. One common application of these regulators is 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: micro-power shutdown capability and output UVLO detection where Flag pin is switched low when output is below 5% of its nominal point.
