The WL2821 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 WL2821 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. WL2821D105-4/TR
