R5531V002

Apr. 2003 R5531V002 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.
