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. PIN CONFIGURATION (TOP VIEW) COLLECTOR OUTPUT GND
