Descriptions
The WL2805 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.
SOT-23-3L
SOT-23-5L
The WL2805 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 WL2805 regulators are available in
SOT-23-3L packages. Standard products are Pb-free
and Halogen free products.
