OmniVision WL2855K CubeChip Image Sensor ASIC Camera
Descriptions
The WL2855K series are high accuracy, low noise, 12V Input, 500mA, 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.
The WL2855K 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 WL2855K regulators are available in standard SOT-89-3L Package. Standard
products are PBS-free and Halogen-free.
