(1) Line regulation is measured with V_IN = V_OUT(NOM) + 1.5 V or 2.5 V (whichever is greater)

(2) V_DO is measured with V_IN = 95% x V_OUT(nom) for fixed output devices. V_DOis not measured for fixed output devices when V_OUT < 2.5 V. For adjustable output device, V_DO is measured with V_FB = 95% x V_FB(nom)
