(1) VDO is measured with VIN = 0.98 × VOUT(nom).
(2) Start-up time = time from EN assertion to 0.95 × VOUT(nom) and load = 47 Ω.
(3) Dropout is only valid when VOUT ≥ 2.8 V because of the minimum input voltage limits.
(4) Measured with VIN = VOUT + 3 V for VOUT ≤ 2.5 V. Measured with VIN = VOUT + 2.5 V for VOUT > 2.5 V.
