Descriptions
The WL2815 series are low dropout linear regulators
and optimized to provide a high performance solution
for battery power system to deliver low quiescent
current. The devices offer a new level of cost effective
performance in cellular phones, laptop and notebook
computers, and other portable devices.
DFN1X1-4L
The WL2815 series are designed to make use of low
cost ceramic capacitors which ensure the stability of
the output current, and enhance the efficiency in order
to prolong the battery life of those portable devices.
The WL2815 regulators are available in DFN1x1-4L
packages. Standard products are Pb-free and Halogen
free products.
