DESCRIPTION
The LT®1313 is a member of Linear Technology
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 VCC supply voltage and automatically adjust the
VPP output to match the associated VCC pin voltage when
the VPP = VCC mode is selected.
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.

The q denotes the specifications which apply over the full operating
temperature range.
Note 1: Both VS pins (10, 14) must be connected together, and both
ground pins (1, 5) must be connected together.
Note 2: For junction temperatures greater than 110°C, a minimum
load of 1mA is recommended.
Note 3: The other channel is programmed to the 0V mode (XEN0 =
XEN1 = 0V) during this test.
Note 4: The VCC sense threshold voltage tests are performed
independently.
Note 5: The VPPVALID tests are performed independently.
