WL2003E
300mA, Low noise, High PSRRˈRF LDO
Descriptions
The WL2003E series are 300mA low dropout
linear regulators and optimized to provide a high
performance solution for battery power system to
deliver low quiescent current. The WL2003E series are
designed for portable RF and wireless applications to
deliver ultra low output noise and high PSRR. The
devices offer a new level of cost effective performance
in cellular phones, laptop and notebook computers,
and other portable devices.
The WL2003E 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 WL2003E regulators are available in standard
SOT-23-5L package. Standard products are Pb-free
and Halogen-free
