This works great in a USB charging cirrcuit. It does heat up a lot using higher voltage inputs but thats expected. Overall great product.

as7805a

Used this voltage reg to power a sensitive circuit, low power, and it shorted to input when I disconnected the dc power. Three different AS7805a. I substituted an old LM7805 and it worked normal. This AS7805 is made in Taiwan, BCD semiconductor. May need a diode on the output to prevent reverse voltage from capacitors. ??????? But then you will need a 6 volt reg.
