DESCRIPTION
The LT
Corporation’s PCMCIA driver/regulator family. It provides
0V, 3.3V, 5V, 12V and Hi-Z regulated power to the VPP
pins of two PCMCIA card slots from a single unregulated
13V to 20V supply. When used in conjunction with a PC Card
Interface Controller, the LT1313 forms a complete minimum
component-count interface for palmtop, pen-based and note-
book computers. The two VPP output voltages are inde-
pendently selected by four logic compatible digital inputs
which interface directly with industry standard PC Card
Interface Controllers.
Automatic 3.3V to 5V switching is provided by two inde-
pendent comparators which continuously monitor each
PC card V
VPP output to match the associated V
the VPP = V
Two open-collector VPP VALID outputs are provided to
indicate when the VPP outputs are in regulation at 12V.
The LT1313 is available in 16-pin SO packaging.
