产品概述 返回TOP
The CXLD6420D 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. The CXLD6420D 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 CXLD6420D regulators are available in DFN1x1-4L Package. Standard products are Pb-free and Halogen-free.
