1A VERY LOW DROPOUT POSITIVE

DESCRIPTION

The IRU1206 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.
