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