  • Description

    The R5533 Series switch the VCC voltage among 0V, 3.3V or 5.0V. And the VPP voltage is outputted in between either OFF, 0V, 3.3V or 5.0V conditions. When the VCC or VPP pin are short-circuited to the GND, the minimum current limit protection values are VCC pin=1A and VPP pin=0.2A. R5533 is suitable for standard type of PCMCIA power controllers.
