IRU1209

1A VERY LOW DROPOUT POSITIVE FIXED AND ADJUSTABLE REGULATORS

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.

FEATURES

■ Low Dropout Voltage 500mV at 1A

■ 1% Voltage Reference Accuracy

■ Low Ground Current

■ 1mA Maximum Quiescent Current in Shutdown IRU1207, IRU1208

■ Fast Transient Response

■ Current Limit and Thermal Shutdown

■ Error Flag Signal for Output out of Regulation IRU1207, IRU1208

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
