ELECTRICAL CHARACTERISTICS (continued)
Minimum and maximum values are at V_IN = 2.3V to 4.85V, V_OUT = 3.4V (or V_IN, whichever is higher), EN = 1.8V, VSEL =
1.8V, nBYP = 1.8V, –40°C ≤ T_J ≤ 125°C; Circuit of Parameter Measurement Information section (unless otherwise noted).
Typical values are at V_IN = 3.2V, V_OUT = 3.4V, EN = 1.8V, T_J = 25°C (unless otherwise noted).
