LT1313 Dual PCMCIA VPP Driver/Regulator FEATURES DESCRIPTION n Digital Selection of 0V, V , 12V or Hi-Z The LT 1313 is a member of Linear Technology CC n Output Current Capability: 120mA Corporations PCMCIA driver/regulator family. It provides n Internal Current Limiting and Thermal Shutdown 0V, 3.3V, 5V, 12V and Hi-Z regulated power to the VPP n Automatic Switching from 3.3V to 5V pins of two PCMCIA card slots from a single unregulated n Powered from Unregulated 13V to 20V Supply 13V to 20V supply. When used in conjunction with a PC Card n Logic Compatible with Standard PCMCIA Controllers Interface Controller, the LT1313 forms a complete minimum n Output Capacitors: 1F component-count interface for palmtop, pen-based and note- n Quiescent Current in Hi-Z or 0V Mode: 60A book computers. The two VPP output voltages are inde- n Independent VPP Valid Status Feedback Signals pendently selected by four logic compatible digital inputs n No VPP Overshoot which interface directly with industry standard PC Card Interface Controllers. U APPLICATIONS Automatic 3.3V to 5V switching is provided by two inde- pendent comparators which continuously monitor each n Notebook Computers PC card V supply voltage and automatically adjust the CC n Palmtop Computers VPP output to match the associated V pin voltage when CC n Pen-Based Computers the VPP = V mode is selected. CC n Handi-Terminals n Two open-collector VPP VALID outputs are provided to Bar-Code Readers n indicate when the VPP outputs are in regulation at 12V.
