LP2966的产品详情：

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.

Key Specifications

Dropout Voltage: Varies Linearly with Load Current. Typically 0.9 mV at 1mA Load Current and 135mV at 150mA Load Current
Ground Pin Current: Typically 300μA at 1mA Load Current and 340μA at 100mA 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
