Typically 0.9 m V at 1m A Load Current and 135m V at 150m A Load Current - Ground Pin Current: Typically 300µA at 1m A Load Current and 340µA at 100m A Load Current (with One Shutdown Pin Pulled Low) - Shutdown Mode: Less than 1µA Quiescent Current when Both Shutdown Pins are Pulled Low - Error Flag: Open Drain Output, Goes Low when the Corresponding Output Drops 10% Below Nominal - Precision Output Voltage: Multiple Output Voltage Options Available Ranging from 1.8V to 5.0V with an Ensured Accuracy of ±1% at Room Temperature DESCRIPTION The LP2966 dual ultra low-dropout (LDO) regulator operates from a +2.70V to +7.0V input supply. Each output delivers 150m A over full temperature range. The IC operates with extremely low drop-out voltage and quiescent current, which makes it very suitable for battery powered and portable applications. Each LDO in the LP2966 has independent shutdown capability. The LP2966 provides low noise performance with low ground pin current in an extremely small VSSOP-8 package (refer to package dimensions and CONNECTION DIAGRAM for more information on VSSOP-8 package). A wide range of preset voltage options are...
