Descriptions
The WL2801E 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.
SOT-23-5L
The WL2801E regulators are available in standard
SOT-23-5L packages. Standard products are Pb-free
and Halogen-free.
