LM2775 na'ura mai jujjuyawar wutan lantarki ce mai daidaitawa wanda ke samar da ƙarancin ƙarfin fitarwa. LM2775 na iya samar da har zuwa 200 mA na fitarwa na halin yanzu a kan kewayon shigarwar 3.1-V zuwa 5.5-V, da kuma har zuwa 125 mA na fitarwa na yanzu lokacin da ƙarfin shigarwar ya kasance ƙasa da 2.7 V. A ƙananan ƙarfin fitarwa, LM2775 na iya rage ƙarfin halin yanzu ta hanyar aiki a cikin yanayin mitar bugun jini (PFM). Ana iya kunna ko kashe yanayin PFM ta hanyar tuƙi fil ɗin PFM zuwa babba ko ƙasa. Bugu da ƙari, lokacin da LM2775 ke cikin rufewa, mai amfani zai iya zaɓar a ja wutar lantarkin fitarwa zuwa GND ko a bar shi cikin yanayin rashin ƙarfi ta hanyar saita fil ɗin OUTDIS babba ko ƙasa.
