SKUWL2848E
The WL2848E series are high accuracy, low noise, high speed, high PSRR, low dropout CMOS Linear regulators with high ripple rejection. The devices offer a new level of cost effective performance in cellular phones, laptops, notebook computers, and other portable devices.
The WL2848E series support the soft-start which prevents input inrush current. The series also have the fold-back maximum output current which depends on the output voltage. The current limit function serves both as a short circuit protection and as an output current limiter.
The WL2848E regulators are available in a standard SOT‑23‑5L package. Standard products are Pb-free and Halogen-free.
