R5531V002
PCMCIA Power Controller
I
DESCRIPTION
The R5531V002 switches between the three VCC voltages (0V/3.3V/5.0V) and the V
PP
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.
