illustrate
The LP2966 dual ultra-low dropout (LDO) regulator supplies from 2.70 V to 7.0 V. Each output provides 150 mA over the entire temperature range. The IC operates with extremely low output voltage and quiescent current, which makes it ideal for battery-powered and portable applications. The LP2966 has independent shutdown capability for each LDO. The LP2966 provides low noise performance with a low current ground pin in a very small MSOP-8 package (refer to Package Dimensions and Connection Diagram for more information on the MSOP-8 package). Each output is available for a wide range of preset voltage options. In addition to the voltage combinations listed in the ordering information sheet, there are increasing minimum order requirements. All 256 voltage combinations are possible.
Main Specifications Dropout voltage: Linearly-varying load current. Both shutdown time less than 1μA quiescent current 1mA load current and 135mV typically 0.9 mV at 150mA load ground pin current: typically 1mA load at 100mA load current (a shutdown pin pulls low), shutdown mode current 340μA300μA: pin pulls low error flag. Open-drain output, becomes low, and the corresponding output drops 10% below the nominal accuracy, output voltage: Multiple output voltages are available, from 1.8V to 5.0V range± 1% accuracy guaranteed at room temperature.
