Low noise, High PSRR, High speed, CMOS
LDO
Descriptions
The WL2836D series is a high accuracy, low noise,
high speed, high PSRR, 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 WL2836D 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 WL2836D regulators are available in standard
DFN1x1-4L Package. Standard products are Pb-free
and Halogen-free.
