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 fea-
tures of the family of the parts are: micro-power shut-
down capability and output UVLO detection where Flag
pin is switched low when output is below 5% of its nomi-
nal point.
