5-PIN SOT-23 5. 0V SYSTEM FIXED OUTPUT VOLTAGE DC-DC CONVERTER DESCRIPTION
M62291GP is an integrated circuit designed as 5V 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 570uA(typ. ) Especially this is most suitable for localized power source such as audio equipments, and so on as converter from 12 to 5V system.
