5-PIN SOT-23 3V SYSTEM FIXED OUTPUT VOLTAGE DC-DC CONVERTER DESCRIPTION
M6227XGP is an integrated circuit designed as fixed output voltage 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.
