DESCRIPTION

The US1206 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 available only and the dropout voltage is less than 1V, exceeding the minimum dropout characteristics of NPN/PNP hybrid regulators. One common application of these regulators are where input is 3.3V and a 2.5V output is needed.

FEATURES

■ Low Droput Voltage (500mV at 1A)

■ 1 Voltage Reference Accuracy

■ Low Ground Current

■ 10uA Quiescent Current in Shutdown

(US1207,1208)

■ Fast Transient Response

■ Current Limit and Thermal Shutdown

■ Error Flag Signal for Output out of Regulation

(US1207,1209)

■ Pin Compatible with MIC39100/101/102 series

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 SMPS
