Low noise, High PSRR, High speed, CMOS
LDO
Descriptions
The WL2820D 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.
DFN1X1-4L
The WL2820D 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 WL2820D regulators are available in standard
DFN1x1-4L Package. Standard products are Pb-free
and Halogen-free.
