Note 1: Limits to -40°C are guaranteed by design.
Note 2: 1.8V is the minimum limit for proper HOLD functionality.
Note 3: Dropout is defined as V_IN - V_{OUT_LDO} when V_{OUT_LDO} is 98% of the value of V_{OUT_LDO} for V_IN = V_{OUT_LDO} + 1.5V.
Note 4: Maximum output current may be limited by the power dissipation of the package.
