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 VIN - VOUT_LDO when VOUT_LDO is 98% of the value of VOUT_LDO for VIN = VOUT_LDO + 1.5V.
Note 4: Maximum output current may be limited by the power dissipation of the package.
