DESCRIPTION
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 CONNECTION DIAGRAM 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.
