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.
APPLICATIONS
2.5V Supply from 3.3V Input for the new
generation of Logic ICs
Computer Mother Board, Add-On Cards
High Efficiency Post Regulator in Switch Mode
Power Supply (SMPS)
