Descriptions
The WL2810 series is a high accuracy, low noise, high
speed, low dropout CMOS Linear regulator with high
ripple rejection. The devices offer a new level of cost
effective performance in cellular phones, laptop and
notebook computers, and other portable devices.
SOT-353
DFN1X1-4L
The WL2810 has the fold-back maximum output
current which depends on the output voltage. So the
current limit functions both as a short circuit protection
and as an output current limiter.
The WL2810 regulators are available in standard
SOT-353 package and DFN1x1-4L Package. Standard
products are Pb-free and Halogen-free.
