PCMCIA Power Controller
IDESCRIPTION
The R5531V002 switches between the three VCC voltages (0V/3.3V/5.0V) and the VPP voltages (off/0V/3.3V/5.0V). If VCC
pin or VPP pin may be clamped to the GND, short current limit works at 1A(Min.) for VCC and 0.2A(Min.) for VPP.
The R5531V002 is suitable for standard PCMCIA power controllers.
