377 Regulator ICs PCMCIA / flash memory power supply BP5310 The BP5310 is a DC / DC converter for supplying power to PCMCIA flash memory. From a power supply (5V) for PCMCIA operations, the IC supplies a voltage for programming operations (12V). Applications Personal computers, CD-ROM players, portable information devices, and other PCMCIA-slot equipped devices Features 1) Designed to provide power for PCMCIA / flash memory programming operations (output voltage = 12V ± 5%; output current = 120mA) 2) The 5V operating voltage is same as the IC memory card operating voltage. 3) Built-in short-circuit protection circuit. 4) Compact 9-pin SIL package. 5) Surface mounting is possible because parts are con- centrated on one side.
