产品描述

The LP2966 dual ultra low-dropout (LDO) regulator operates from a +2.70V to +7.0V input supply. Each output delivers 150mA 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 for more information on VSSOP-8 package). A wide range of preset voltage options are available for each output. In addition, many more are available upon request with minimum orders. In all, 256 voltage combinations are possible.

产品特性
