general purpose DC-DC converter.
Integrating peripheral components in ultrasmall 5-pin SOT23 package
allows for simplified external circuit and compact low cost design.
This IC is applicable to portable equipments due to low circuit current
500uA(typ.)
Especially this is most suitable for CD-ROM, and so on as converter
from 5 to 3V system.
