R5534V
May. 2005
PCMCIA Power Controller
sDESCRIPTION
The R5534V switches between the three VCC voltages (0V/3.3V/5.0V) and the VPP voltages (off/0V/3.3V/5.0V).
The R5534V has two sets of VCC output and VPP output each, therefore it fits dual slot models. If VCC pin or VPP pin
may be clamped to the GND, short current limit works at 1A(Min.) for VCC and 0.15A(Min.) for VPP.
The R5534V is suitable for standard PCMCIA power controllers.
