The LT
1312 is a member of Linear Technology
Corporation’s family of PCMCIA drivers/regulators. The
LT1312 provides 0V, 3.3V, 5V, 12V and Hi-Z regulated
power to the VPP pin of a PCMCIA card slot from a single
unregulated 13V to 20V supply. When used in conjunction
with a PC card interface controller, the LT1312 forms a
complete minimum component-count interface for palm-
top, pen-based and notebook computers. The VPP output
voltage is selected by two logic compatible digital inputs
which interface directly with industry standard PC card
interface controllers.
Automatic 3.3V to 5V switching is provided by an internal
comparator which continuously monitors the PC card V
CC
supply and automatically adjusts the regulated VPP out-
put to match V
CC
when the VPP = V
CC
mode is selected.
An open-collector VPP VALID output is driven low when
VPP is in regulation at 12V.
The LT1312 is available in an 8-pin SO package.
