SKUWL2855E
The WL2855E series is a high accuracy, low noise, 12V input, 300 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 WL2855E 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 WL2855E regulators are available in standard SOT-23-5L Package. Standard products are Pb-free and Halogen-free.
