Highlights:

It is very simple to use, only two external resistors are needed to set the output voltage. Its linear adjustment rate and load adjustment rate are also better than the standard fixed voltage regulator. Its output voltage is linearly adjustable in the output range, and its ripple is very small. It is suitable for power supply, small signal amplification and low noise and low current environment.
