... DESCRIPTION The IP1523 is a dual output voltage series regulator with output on/off control function. The nominal output voltages are 3.3V and 2.0V,respectively. The 3.3V regulator can provide the output current up to 550mA. While the 2.0V regulator can provide up to 500mA. When the IP1523 becomes off, all the output voltages are shut down ...
