WL2808E
Low noise, High PSRR, High speed, CMOS LDO
Descriptions
The WL2808E 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 current limiter's fold-back circuit also operates as a short circuit protection and an output current limiter at the output pin.
The WL2808E
regulators are available in standard SOT-23-5L packages. Standard products are Pb-free and Halogen-free.
