The HX2031 is 200mA low dropout linear
regulator optimized to provide
a
high
performance solution to low power system.
The device offers a new level of cost-effective
performance in cellular phones, laptop and
notebook
computers，and
other
portable
devices. Proprietary design techniques ensure
high performance.
The HX2031 is designed to make use of low
cost ceramic capacitors which ensure the
stability of the output current, and enhance the
efficiency in order to prolong the battery life of
those portable devices.
The HX2031 regulators are available in the
industry standard DFN1.2*1.6-4L power
packages (or upon request).
