SKUWL2855K
The WL2855K series are high accuracy, low noise, 12V input, 500 mA, 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 Pb-free and Halogen-free.
