(1) Line regulation from Input of the LDO to the final output of the LDO.

(2) V_DO is measured with V_IN = 0.95 × V_OUT(nom) for fixed output voltage versions. V_DO is not measured for fixed output voltage versions when V_OUT ≤ 3.1 V. For the adjustable output device, V_DO is measured with V_FB = 0.95 × V_FB(nom).

(3) V_{DO(MID_OUT)} is measured with V_IN = 0.95 × V_{MID_OUT(nom)} for Mid output voltages.
