(1) Line regulation is measured with VIN = VOUT(NOM) + 1.5 V or 2.5 V (whichever is greater).
(2) VDO is measured with VIN = 95% x VOUT(nom) for fixed output devices. VDO is not measured for fixed output devices when VOUT < 2.5 V.
(3) IPULLDOWN is measured with VIN = 1.8 V (lower than UVLO falling threshold, with LDO in disabled state) and 2.5 V applied on VOUT externally.
